I was once explaining to someone in the US why transactions in Mexico and Brazil take a tumble and start to be rejected at a much higher rate than usual due to banks being more stringent after 10 PM as its much more likely these would be fraud/scam/crime in general in these countries and they were amazed that this was a thing.

Its sad that these scams are so widespread today that a heavy handed approach like this is necessary. Unfortunately doing these attacks is incredibly cheap :(

esafak•1h ago
To me it suggests they don't have the technical- and financial means to detect fraud.
dlisboa•38m ago
Unfortunately the number of different financial scams is the highest in the world in these countries. US and EU the banks wouldn’t have the capabilities either, it’s simply too much to deal with. You can’t flag everything as fraud.

It’s also a different kind of enemy. The biggest crime organization in Brazil has switched their primary focus from drug running to financial scams. They invest millions and set up legitimate companies with hundreds of employees to facilitate these schemes.

kattagarian•58m ago
It's probably one of the biggest criticism about PIX, the Brazilian method of transferring money: it's too easy. Early on, kidnappers started taking people off the streets and forcing them to transfer all their money, because victims had no choice but to give their password, and there was no limit on the transfer amount.
dkga•48m ago
Yes, but the Central Bank of Brazil caught up quickly.

Criminals always find a way Decades ago, there was a popular activity called "Paseos Millonarios" (More or less, Millionare Rides) where criminals at night picked up a victim coming out of an ATM, and took him to several other ATMs around, everytime drawing non-suspicious amounts of money. The criminals didn't even need the PIN. They neither entered the ATM hut because only the card holder was sent in.

The final solution was disabling the ATM network durimg night, except the ones located in safe places. Showing you are drawing money in a hurry in a lone hut in the night was a bad idea, anyways.

jajko•34m ago
Unlimited amount? Sure, I can easily see some non-standard situation where its very beneficial (ie once-a-decade home reconstruction). But only on a limited account having only the amount I don't mind exposing, which normally is very low.
hnlmorg•1h ago
I opened that link expecting to be outraged but instead finding myself sympathetic to their solution.

High value transfers should be subject to additional scrutiny to confirm it’s legitimate.

The hard part is making sure you balance that well enough so that you’re protecting against malaise without the bank then becoming a consumer problem themselves.

It will be interesting to see how well this works.

They froze tons of accounts without warning, it was not just a matter of setting daily limits
refulgentis•1h ago
If I understand correctly*, they froze 3 million accounts tied to 177K mules.

Couldn't find anything that indicated there was a mass freezing of legitimate accounts, or a singular complaint of an incident of that happening.

* Can't copy paste...is the article an image!?

debugnik•59m ago
> is the article an image!?

I can't check right now, but I'm guessing they set `user-select: none` in CSS.

ameliaquining•58m ago
Article's not an image, it's regular HTML text content. The site just uses some extremely obnoxious JavaScript that blocks text selection, right-clicking, and the view-source and developer tools keyboard shortcuts. The latter is especially pointless since anyone who knows about those features also knows that they can be accessed via the browser menu, which JavaScript can't block.
hedora•47m ago
Or, at least in iOS/macOS, just take a screenshot, then select the text from there.
hnlmorg•1h ago
It does say those were tied to “mules”, so freezing those accounts is the right course of action.

In fact the last thing you want to do is give criminals warning that you’re going to freeze their accounts. I’d imagine that would be extremely counterproductive for everyone bar those criminals.

kijin•1h ago
The article is unclear about when the freezings took place, but the sentence starting with "By July" seems to suggest that 3 million is the cumulative total of all the accounts that were frozen from January to July. So it probably wasn't a sudden mass freezing, just constant whack-a-mole.
Stevvo•1h ago
New customers will be defined as "high-risk" with, a separate classification from "vulnerable" which is for under 15s and over 65s. The limit for these "high-risk" customers is 50000 baht a day, which is surely going to be inconvenient to deal with if you ever need it, e.g. for medical bills.
ameliaquining•56m ago
Medical providers are probably okay with getting paid in 50,000-baht daily installments if necessary?
Ekaros•46m ago
1 344,17 Euro

Which to me seems entirely reasonable limit. Such transactions are relatively rare.

StopDisinfo910•41m ago
That’s two months of the country median income. I’m pretty sure medical providers will be okay.

That’s mostly annoying for inter accounts movement if you move money around a bit but I think you would get higher capacity if you are concerned.

cf100clunk•1h ago
I'm assuming 3M (née Minnesota Mining and Manufacturing Company) accounts have not been affected.
hnlmorg•1h ago
The title would then say “3M’s accounts” to denote ownership.
JumpCrisscross•1h ago
Would note that 3M is an unconventional was of representing 3mm or 3mn.

I got downvoted due to someone's unconventional reading. You win some, you lose some.

You’re downvoted because you’ve strongly indicated you didn’t read the article.

That's an unwarranted assumption.
hnlmorg•55m ago
I’ve never seen ‘mm’ nor ‘mn’ used in British English, where ‘m’ is a common abbreviation for “million”. But this might be a localisation.

Wikipedia does recognise ‘m’ as an abbreviation: https://en.m.wikipedia.org/wiki/1,000,000

It’s definitely open to confusion but generally if you already known that abbreviation exists then one can usually deduce how to interpret that abbreviation from the context of the sentence. In this case, it’s a financial headline so I assumed it was “million”.

JumpCrisscross•24m ago
> Wikipedia does recognise ‘m’ as an abbreviation

The lower-case m is used in British English. Upper case M can be used, but it’s unnecessarily ambiguous and close to wrong in American English.

HN plays shenanigans with the capitalisations in headings.
dboreham•53m ago

What's the real reason? Fraud has been around forever now. How is it that people were able to create so many mule accounts in the first place? What sort of KYC was going on? Why start limiting bank accounts without warning?

So many questions...

Update: my Thai friend just wrote me this:

"Not in trouble, it's the Chinese and Russians money laundering. Every Russian has had their accounts suspended, this was about half a year ago, now they are slowly doing the Chinese and Brits too. Vietnam is not much better, also suspending all foreigners accounts until you can prove you have a trc here."

We've been having a similar fraud issue here in South Korea as well. These criminals call vulnerable people, impersonate bankers or government officials, and social-engineer them into trasferring money. Some even pretend to have kidnapped your child, play AI-generated voice of a sobbing kid, and demand ransom.

Fraud has always been around, but I think a few recent developments have exacerbated the problem. KYC has been relaxed a lot since Covid, so you can open a whole bunch of accounts with just an image of an ID card. Lots of elderly people now have access to mobile banking, so they don't have to visit a physical branch where a clerk can flag suspicious transfer requests.

Bank accounts in South Korea now start with a daily transfer limit of 1 million won (about $700), even lower than the 50k bhat limit that the Thai government has instituted.

  KK Park – a vast, heavily guarded complex stretching for 210 hectares (520 acres) along the churning Moei River that forms Myanmar’s border with Thailand.. with its on-site hospital, restaurants, bank and neat lines of villas with manicured lawns, looks more like the campus of a Silicon Valley tech company than what it really is: the frontline of a multibillion-dollar criminal fraud industry fuelled by human trafficking and brutal violence.. Myanmar, Cambodia and Laos have in recent years become havens for transnational crime syndicates running scam centres such as KK Park, which use enslaved workers to run complex online fraud and scamming schemes that generate huge profits.
sirn•42m ago
> How is it that people were able to create so many mule accounts in the first place? What sort of KYC was going on?

They pay a low-income/no-income person a small fee (possibly monthly) to let them borrow their account. Sadly, people who would fall into this are not hard to find in Thailand.

> What sort of KYC was going on?

There are accounts that are grandfathered in and don’t require KYC but have been able to access online banking, etc. Mine is such, and my bank (BAY) is discontinuing that particular loophole at the end of this month. (I'm in Thailand right now to do this KYC, despite having not come back here for the last 6 years.)

ameliaquining•1h ago
The truncated headline is extremely misleading; it makes it sound like they're having a currency crisis, rather than this being an anti-fraud measure. (I'm not finding any indications in other sources that there is a currency crisis or that the anti-fraud rationale is pretextual, though I could have missed something.)

(ETA: HN title has been re-edited, previously didn't have the "to curb fraud" clause.)

JumpCrisscross•1h ago
Yeah, flagged for editorialisation. (EDIT: Unflagged for mentioning fraud. Would also recommend changing the ambiguous 3M to 3mm or 3mn.)
hnlmorg•47m ago
It’s a long headline. I bet the editorialisation was reluctantly done to work around HNs character limit.

If you have a better suggestion for an abridged headline then you could share and hopefully the submitter can still update this submission.

I've read the headline and my first thought was, "they're overdue on tackling fraud", but perhaps it should be clarified.
StopDisinfo910•46m ago
That’s not only closure, that’s global currency control. Every account is now subjected to a transfer limit.

Even if the anti-fraud motif is genuine, that’s a pretty extreme amount of control. Not that it’s in any way strange coming from Thailand. Foreign exchange and capital inflow and outflow are already controlled.

lambda•37m ago
When discussing the headline on HN, can you please quote the headline that you are discussing? Headlines are commonly edited by mods without any history, so it's hard to tell if you're discussing the current headline or something else.

Assistant BOT Governor.. acknowledged that current procedures for identifying and freezing suspected “mule accounts” need refinement to prevent harming innocent customers. Many account holders have taken to social media to express frustration over being unable to access their money or conduct business after transfers from unknown sources triggered automated freezes.

this wasn't a swift action overnight

they could be blocking this many accounts on a yearly basis just from scam reports at the police station

or more which seems to be the case recently, but not overnight

this is bad article

I live in Thailand, many expat accounts have been closed down, making it very hard to pay bills etc. in the country. That will form part of the 3 million. Huge overreaction that will dent the economy and will no doubt be flip-flopped on in a few months time.

alephnerd•15m ago
Having seen the kinds of expats there are in Thailand, good riddance.

Tourism is a significant portion of the economy, but not overwhelming [0].

Tourists and "expats" in Thailand overstate their importance in the country. Some bogan who wants to get drunk on Songsom and spend maybe $100-300/mo isn't moving the needle economically for Thailand.

Japanese and Korean expats (as in those actually brought in by Japanese and Korean companies as part of the FTA to transfer expertise) are a different story.

Thailand has been an industrial country for decades now. Most of your car parts (and even cars) in Australia, a portion of global semiconductors, oil refining, polymers, and other intermediate parts have been manufactured, assembled, or packaged in Thailand for decades.

Can you elaborate on the kind of expats that are undesirable? I don't know what specific types of people you might be referring to
bjcy•14m ago
It’s important to note that many of the expat accounts have been closed down due to the laxity of individual bank branches in enforcing their own policies, which were taken advantage of by nefarious actors. Many expats attempt to open bank accounts on tourist visas (which include the recently popular Destination Thailand Visa for digital nomads) without proper identification, and though allowed in the past, is now being restricted. One can argue about the classification of visas and the dissonance between economic goals and immigration policy, but for Thais, this is a long overdue enforcement action especially as it regards to scams targeting an older generation. Yes, it significantly impacts honest expats looking to stay beyond the short-term, but there is a way to doing things in Thailand that requires guests to adapt to their hosts, of which accepting the reality of Thailand’s political situations is an important part.

Can someone explain why MM means millions, and not just M, 3M ==3 millions?
walterbell•30m ago
https://accountinginsights.org/how-to-abbreviate-million-in-...

  The abbreviation “M” for million can lead to confusion in finance. Historically, “M” derives from the Latin word “mille,” meaning “thousand.” As such, it has traditionally been used in some accounting or construction contexts to denote a thousand. For example, $5M could historically represent $5,000, creating ambiguity.

  To represent one million in finance, the abbreviation “MM” is widely used. This notation originates from “mille mille,” meaning “thousand thousands” in Latin, equating to one million. This clarity makes “MM” a preferred choice in financial statements and reports. 

  Other abbreviations for million, such as “mn” or “mln,” are also encountered.. The Financial Times, for example, adopted “mn” for millions to improve accessibility for text-to-speech software. While these alternatives exist, “MM” remains a prevalent and widely understood abbreviation for million in American finance.

I wonder in the crypto based future if there will be any safeguards to avoid scams and fraud. Instant settlement is not a good thing for me, Ideally any transaction over $1000 should take a week and can be cancelled. Transactions over $100k I'd like to go to a physical location and prove my identity.
ronsor•27m ago
In many cryptocurrencies, you can cancel a transaction before the first confirmation by paying a (relatively) small fee. Your other points defeat the purpose of most crypto, though.

Does "MM" usually stand for "million"? In German we have "Millionen" and then "Milliarden", but in English that is "Billion", so "MM" cannot stand for "Milliarden" either. And "Mega" already is *10^6, but only has 1 "M". So at first naturally I read "Million Million", but then thought: "What? There is no way they have that many accounts!"

It is a very confusing way to write the number and no explanation seems to fit, other than "There is a second 'M' to avoid clash with the company name '3M'.". Is that the explanation?

mhluongo•13m ago
It comes from finance - the rest of us just use "M" for million. I believe it's from Roman numerals (MM = thousand * thousand).

The funny thing is, that MM in roman numerals means 2000.
