someone on a discord server I was on a long time ago showed me this ungodly captcha that's common on darknet forums. It's like the only captcha I can think of in the ballpark for being this straight up bullshit.
For the record, this was a "no evil" forum (basically, stuff like drugs or hacking or gambling are fine but CSAM or hitmen, still banned) so it's not like they were doing anything monstrous. Mostly just there to see darknet drug dealers getting into arguments on Dark Reddit.
