Does 4Chan also have bot BEHAVIOR detection (e.g. unnatural mouse movements)that google captcha has?
It does not, at least not once you pass the Cloudflare Turnstile challenge (which can be done with an API as well.)

Makes me wonder what comes next. Could we create a forum where every member must do a 15 minute video interview with a moderator? I know this "doesn't scale" but I think it could make for a funny gimmick.
private torrent trackers are/were doing that. It was really just to make sure you understood how p2p culture works and what the expectations are, and really easy to pass if you just followed a guide. However, I did see many people fail their interview.
Was there ever video interviews? Admittedly I wasn’t really paying attention but back when I was getting into what it was only IRC, and these days it still seems to be IRC anywhere that does interviews (otherwise class-restricted forum invites).
Re: Breaking the 4Chan CAPTCHA
#143I remember trying to use 4chan once and i couldn't even pass through the captcha.
I remember using it before it had a captcha
There was a chaotic neutral time in my life where I used it daily for an extended period of time; and then found myself out of that rut and would only go back to see unhinged takes on a particular current event that I was interested in seeing the hivemind's thoughts on. Each and every time I went back, and tried to contribute to a thread, the Captchas and the CloudFlare checks were increasingly intrusive.
During this election, I completely gave up even trying to participate and just lurked.
Re: Breaking the 4Chan CAPTCHA
#144I suspect really strongly that the available characters in the 4chan captcha were chose to be able to spell out the most racist/nazi/extreme slurs and slogans imaginable. For instance, not all numerals are ever used, but 1, 4, and 8 are. K is often there, and whatever the algo is, pseudorandom or not, it often doubles/triples characters. I've personally seen "kkk" twice over the years. Mind you, it does seem random. But even randomly, these must happen often enough to set that crowd off, they make a game of posting a screenshot of the "good ones".

#145Appropriate response by 4Chan to this: simplify the human work given that anyway it's simple to solve via NNs. We are at a point where designing very hard captchas has high probabilities to increase the human annoyance without decreasing the machine solvability.
What is NN?
"AI" but pre-COVID

#146Parsing the visualization data, within a JSON script tasked with parsing it is a complex endeavor when the site requires verifying email.
If the JSON file is corrupt, it shows the following if tt1 and cd do not align.

All the worst slurs I can think of in my limited vocabulary can't even be spelled with the characters available. I suspect the opposite - they might have been chosen to avoid spelling things like that.

I dont recall ever seeing that. I dont think anyone doing piracy wants to be photographed or videoed lol. I did get in mumble with some community members but it was just a hangout.

#150[meta] what blog site is this? Is it a joint among authors? I can’t find more information on their GitHub. Looks neat.
I (veritas) run the blog but accept contributions from anyone. The blog itself is open source :-) https://github.com/nullpt-rs/blog
