A refreshing (and amusing) attitude versus getting angry and venting on forums about aggressive crawlers.
I don't think JPEG data is compressed enough to be indistinguishable from random.
SD VAE with some bits lopped off gets you better compression than JPEG and yet the latents don't "look" random at all.
So you might think Huffman encoded JPEG coefficients "look" random when visualized as an image but that's only because they're not intended to be visualized that way.

Some kind of statement piece
Just because traffic is coming from thousands of devices on residential IPs, doesn't mean it's a botnet in the classical sense. It could just as well be people signing up for a "free VPN service" — or a tool that "generates passive income" for them — where the actual cost of running the software, is that you become an exit node for both other "free VPN service" users' traffic, and the traffic of users of the VPN's sibling commercial brand. (E.g. scrapers like this one.)
This scheme is known as "proxyware" — see https://www.trendmicro.com/en_ca/research/23/b/hijacking-you...
Proxyware is more like a crypto miner — the original kind, from back when crypto-mining was something a regular computer could feasibly do with pure CPU power. It's something users intentionally install and run and even maintain, because they see it as providing them some potential amount of value. Not a bot; just a P2P network client.
Compare/contrast: https://en.wikipedia.org/wiki/Winny / https://en.wikipedia.org/wiki/Share_(P2P) / https://en.wikipedia.org/wiki/Perfect_Dark_(P2P) — pieces of software which offer users a similar devil's bargain, but instead of "you get a VPN; we get to use your computer as a VPN", it's "you get to pirate things; we get to use your hard drive as a cache node in our distributed, encrypted-and-striped pirated media cache."
(And both of these are different still to something like BitTorrent, where the user only ever seeds what they themselves have previously leeched — which is much less questionable in terms of what sort of activity you're agreeing to play host to.)
I was very excited 20 years ago, every time I got emails from them that the scripts and donated MX records on my website had helped catching a harvester
> Regardless of how the rest of your day goes, here's something to be happy about -- today one of your donated MXs helped to identify a previously unknown email harvester (IP: 172.180.164.102). The harvester was caught a spam trap email address created with your donated MX:
Does it? Encryption increases entropy, but not sure about compression.
Total information entropy - no. The amount of information conveyed remains the same.
That said, these seem to be heavily biased towards displaying green, so one “sanity” check would be if your bot is suddenly scraping thousands of green images, something might be up.
