Does Reddit have an astroturfing problem? What the data suggests

https://www.petervijeh.com/projects/reddit-astroturf
43•p-s-v•56m ago

Comments

asg172•40m ago
A truly load-bearing article that reassures us that Reddit is not astroturfed.

Of course, AI coding agents, which the author works on, would also never be astroturfed on Reddit!

You know, astroturfing on Reddit also comes from long time accounts with moderator support.

oceansky•35m ago
I don't think the article is reassuring it is not astroturfed? He studied only a small case, for a brand on the smaller side, and found significant amount of bots.

If you see a single sheep on an island, it is safe to assume there is more than one sheep living on the island.

0xy•39m ago
Yes, yes it does. There's astroturfing of every variety: political, brands, image rehab, you name it.

Just look at how often Bill Gates gets glazing articles posted which receive suspicious rankings. None of the comments mention the Epstein-sized elephants in the room.

Politics is even worse, and it's useless as a platform for taking political temperature. Numerous companies openly admit to this activity and Reddit has never commented on this practice.

rafram•30m ago
reddit is an echo chamber when it comes to most topics, and politics are probably the worst of all. Back in the Gamergate days it was all MRA types (throwback!); in 2016 it became 50% Bernie and 50% Trump; these days it's mostly mainstream liberal. I assume the actual political makeup of the user base hasn't changed that much in that time, but people who obsessively refresh and upvote/downvote posts based on their politics have an outsize impact on what comes to the top. I'm sure there's some impact from automated astroturfing, but humans drive it.

No serious person would ever suggest using it to take the "political temperature" of society at large. It's about as useful as Nextdoor for that.

ChrisRR•26m ago
Damn I haven't seen a Bill Gates conspiracy theory in a long time. What a throwback
neilv•39m ago
> REDCmts sells one Reddit comment for $9.99 and 100 for $699.99, from what it calls "real, aged accounts", and shows a gallery of brand mentions it says it delivered. Soar says its accounts are "aged and manually warmed" for weeks before a single brand mention. Bazzly advertises automated replies to every post that looks like someone shopping.

Why doesn't Reddit make sure that shilling is disallowed by their ToS, and then sue these companies and all their customers?

add-sub-mul-div•33m ago
For the same reason Amazon doesn't solve fake reviews. Their business needs the content and they're confident that the people who haven't left for better options will remain undiscerning.
noncoml•27m ago
> left for better options

Please name one

Genuinely asking

KingOfCoders•24m ago
In Germany e.g. Galaxus works fine for many things. Also eBay surprisingly works better for many things because it has more filters, e.g. if you want to buy wood or window shades etc.
zelphirkalt•11m ago
eBay has become a cesspool though, with their silly login requiring phone number and so on. I still remember I had a completely fine Kleinanzeigen account at the beginning of the Pandemic, because I wanted to offer math and computer stuff help for students and put an ad for that on kleinanzeigen. (Didn't ever get a request that was worth taking seriously.) Then at some point later, I suddenly was no longer allowed to log in, unless I disclose my phone number. What a shit. Since then that account sits stale or might already be deleted.
PyWoody•37m ago
I gave up on any product related reviews on Reddit a decade ago. It can still be useful for guides that may describe what type of products you should look into, e.g., woodworking tools, skincare, etc.

For product reviews, I've been using GearLab (https://www.techgearlab.com/) for years with pretty reliable results. I have no affiliation with them.

close04•33m ago
> For product reviews, I've been using GearLab (https://www.techgearlab.com/) for years with pretty reliable results. I have no affiliation with them.

Why would you assume any website is immune to this problem of bots and fake or paid reviews? Bots are so cheap now and smart enough to pass as realistic humans.

Even with good intentions, money runs out eventually (they say no ads and no sponsored content) and someone with deep pockets will exploit this.

Eventually everyone will just have to implement the foolproof solution of putting in the rules that saying that their website has a problem is "a semi-noob illusion, as old as the hills" and be done with it.

PyWoody•30m ago
Because they are not a review aggregator? They purchase the products themselves, do extensive testing, and then publish their results. You can find more about their process on their About page here: https://www.techgearlab.com/about.
close04•13m ago
I was editing my comment but I can go into detail about what I mean here.

I understand how they operate (it's in the middle of their main page) but that actually makes it more difficult for them. The site commits to test thousands of products each year and they don't do sponsored content, free samples, or ads.

They're walking on a beaten path, see Rtings [0] (even the methodology and visual style, which is a good thing). Everyone eventually needs to look for alternative revenue streams to support themselves especially when the competition is fierce and doesn't always play fair. Affiliate link revenue is not a reliable long term financing strategy for a review website which has to constantly purchase new stuff and pay qualified reviewers.

I will buy the products from the store that sells it for the lowest price and delivers in my area. Their Amazon.com affiliate links don't contribute anything in that case.

> Adding "reddit" to a knife search still gets you humans, mostly. For a couple of brands, a quarter to a third of the buying advice comes from accounts that mostly recommend that brand. Whether those are fans or paid, I do not know, and after reading their histories I lean toward fans and hold the lean loosely.

Very long write up to unconfidently say I don’t know.

stevekemp•26m ago
For a while people were suggesting that adding "reddit" to queries for shopping advice was a real way to get uncensored/genuine commentary and reviews.

Even the first time I saw the advice I was skeptical, reddit is rife with bots, and fake comments/posts. It's been well-known for almost a decade at this point that there are multiple individuals moderating many communities there, and that kinda power is rife for abuse.

I've been a sporadic reddit reader/poster for a few years, but this past month I've had enough and deleted my account. The main draw was niche-topics, but they've been overrun with AI slop, and even the local communities have become echo-chambers rather than posts of new bands, events, etc. The local newspaper can tell me about those already.

add-sub-mul-div•29m ago
That this was posted by someone who's only here to post his own sites and those sites have never been submitted by another person is like performance art.
rithdmc•27m ago
I think the items listed under "What astroturfing would look like" were a pretty narrow scope. If I were designing a ~spam system~ astroturfing solution, I'd engineer out these four simple indicators as soon as I could.

* Those accounts naming one brand almost every time they name any. * Thin accounts: few comments, low scores, no real standing in the subreddit. * Young accounts, or accounts with histories that are hidden or wiped. * Links to a store or an affiliate page.

gwbas1c•25m ago
> Unfortunately, advertisers are getting smarter and using bots...

I honestly thought this was a nag asking me to turn off my ad blocker!

asksomeoneelse•23m ago
Niche topics like linux feel somewhat safe from bots. But the last time I checked the more popular subs.. yikes..

When I see 2-weeks old account "Incendiary-Leg-8592" responding to a post by another weeks old user "Pivotal-Kitchen-0498", I have a hard time believing they are humans behind them.

jmuguy•17m ago
I'll bet there's a browser extension to hide comments and posts from those auto generated user names. Like maybe you end up not seeing something interesting because someone used a throwaway account, but otherwise I don't really care what someone has to say that can't even be bothered to pick a name.
sixothree•15m ago
It's crazy to me they are presenting sluggified account names as something that should be taken seriously. But I guess it doesn't matter because most people just don't notice, and worse, the technology surrounding reddit does not seem to care.
mrweasel•19m ago
Ads, scams, rage bait, trolls... The internet is pretty broken for almost all sites that pretends to carry conversations between actual people.

I don't understand why so many people and companies feel the need to just spam reviews, SEO and questionable ads. It's like almost no one has the idea that may we start with a good product, then we'll tell people about it. It's always a question of what you can have produced cheaply in China and how do we then trick people into buying it.

As it stand you can pretty much assume that if it's advertised, or is promoted on social media, it's going to be a shit product.

To some extend I'd exclude certain types of YouTube reviews, because they frequently aren't paid by the manufacturer and making a video with real people and real data is to expensive to waste on scams.

cucumber3732842•12m ago
>s between actual people.

Only for arbitrary people. Gate kept or low member count communities that exist to facilitate a discussion between appliance repair men, literature enthusiasts, fly tying hobbyists or owners of a particular model of vehicle are largely alive and well (unfortunately a lot of them moved from forums to facebook, but still.

jdw64•19m ago
Isn't there? Especially when crypto was booming, that kind of opinion manipulation definitely existed to deceive people. I've actually seen it in freelance requests before too, and most of the time they run it through phone farms.

I've also heard it happens in some games as well, but either way, the one I can say for certain is crypto.

socializer•18m ago
My impression is that this doesn't show anything. It essentially implies that brand loyalty is equivalent to paid astroturfing, but if you've been around hobby communities on the internet, you know that a lot of people are just brand blowhards. And in any case, by its own admission, none of the results in this article are statistically significant, so it fails to find the effect it implies to have found.

I strongly believe that there's a lot of paid product placement and paid political talking points on Reddit, so it's actually remarkable that this (LLM-generated) article fails to find it. I suspect it's just bad design.

If you're already spending money on tokens, there's a very simple experiment you could do instead: just pay one of these companies to position a made-up product and see what they do.

micromacrofoot•13m ago
some people will expend a surprising amount of effort to justify their personal choices

at this point astroturfing is a given... corporations do it, governments do it, individuals do it... anonymous content in aggregate can not be relied on

HarHarVeryFunny•17m ago
A large portion of the "New LLM release" story comments here on HN also appear to be astroturfing ... would be interesting to see a correlation of comment sentiment to IP-derived geographic location!
consp•13m ago
Sounds interesting but I find it kind of annoying the github source either has been nuked or never existed in the first place.
thimabi•12m ago
Perhaps we can envision a future in which we analyze Reddit data not according to all the positive things people say about a product, but according to the negative things being said.

Shilling can’t prevent dissatisfied customers from voicing their opinions in a properly moderated subreddit, and astroturfing to spread misinformation about a competitor makes companies much more vulnerable to litigation.

wxw•7m ago
IIRC the Reddit founders used bots for initial traffic to skip over the cold start problem. I feel like this bit of lore is actually pretty terrible but is treated as a nice anecdote because it worked.
zulux•5m ago
Yes.

I do it locally to nudge political discourse. Doesn't take much to sway a lot of people.

I'm glad I agree with what I'm doing because its effectiveness is terrifying.

ChrisRR•27m ago
I'm assuming it already falls under rules 2 and 5, content manipulation and deceptive interactions
emdash•25m ago
Obviously it's hard to prove such a thing but I've always wondered if the owners of Reddit actively support having these operations run on their site.

I've seen cases where the admins delete comments that talk about the issue

bsenftner•23m ago
Owners of Reddit also own these companies.
cogman10•20m ago
I think that reddit's recent change to allow hiding comment history is exactly to help support shilling.

It makes it hard to see what's a bot and what's a legitimate account.

kube-system•22m ago
Because it would be a monumental waste of time and money. Even if you could track down the overseas operators doing this, there's not much damages you could sue for, and alternatives would just pop up in their place.
literalAardvark•19m ago
Overseas operators? Nonsense.

I know US people who do this for a living

cogman10•15m ago
Technically this is something the FTC could get involved in as it's illegal to advertise without making it clear you are.

A few years back a bunch of influencers were fined for doing just that.

mingus88•22m ago
Because the only metric that matters for social media is engagement, and a war against active account, no matter the purpose, would make that line go down.

Also, shill accounts prove to advertisers that the platform works to make money. That’s the whole reason Reddit exists.

mountainriver•15m ago
YCombinator is not a social company. They actually do a ton to try to stop this stuff, it's just hard.
micromacrofoot•17m ago
Generally you can't stop them, they're shell companies run from countries that don't care. You spend a lot of time and effort trying to block one and they just spin up another, it's asymmetrical in that you expend more resources to stop it.

reddit wants engagement numbers to grow either way, so that disincentivizes it further

bediger4000•15m ago
Based on what happens everywhere, they're paying reddit for leniency. Pink contracts have been around since Uunet was offering them to Usenet spammers.
rafram•8m ago
Why not? Wirecutter is a cash cow for the Times; if you can keep people's trust, recommending (and affiliate-linking to) products in semi-luxury categories is a lucrative business!
groundzeros2015•11m ago
Why are you answering questions for this site and pointing to their official material?
rafram•7m ago
Presumably because it's a good site and the qualms people are expressing with it here have no basis in reality.

It seems like the parent comment is likely right

rafram•15m ago
These days there are central clearing-houses for affiliate links that support basically every store, for the rare case where a product isn't available on Amazon/Best Buy/etc. Matic seems to use something called Impact.com. I don't see why that would be a concern.
losvedir•26m ago
What's their business model? A priori, I don't trust them because there's no reason for them to give out all that information for free. I assume it's a affiliate marketing / referral revenue stream? I suppose it could be fair within those parameters, but it would mean there's no incentive for them to test products that don't have such a program.

I pay for Consumer Reports, since you actually need a paid subscription to access the data, which makes sense structurally. I don't really know if the reviews are any good, though I've been relatively happy with it. I also paid a subscription for an independent supplement testing lab, but I forget what it's called at the moment.

PyWoody•24m ago

Yes, they work on an affiliated model. From their About[0] page:

GearLab is legit. Their outdoor sibling (https://www.outdoorgearlab.com/) is also great. I think the whole concept of "best" in a product category is fairly flawed, but they do it well; their individual product reviews are even better.
fourside•6m ago
I wasn’t aware of GearLab, thanks for the tip. I will say, though I took a look and it seems like they heavily use Amazon links so they suffer from similar downsides as Wirecutter.

Amazon nowadays is such a crapshoot. A link to a product isn’t reliable. The price could be different than what the review stated, and the link might be for an listing that shows as out of stock. I think GearLab tries to fix this by giving you a link to search results on Amazon instead, but in some ways that’s worse. In the couple of links I tried the reviewed product wasn’t the top result so now it’s up to you to decide which of the links is the real one.

That loses some of the value prop for me because part of what I want from a service like this is to give me a link to a legit product listing. That’s not GearLab’s fault, Amazon makes that very difficult, but it still reduces the utility for me. That said it’s better than nothing which just points to the sad state of affairs in e-commerce today.
