Obviously, the OP is talking about the idea of a second chance, which starts with the fact that people who use AI first get some kind of badge that would tag them, and such a system exists on that other forum, with the addition that each tagged user can pay a certain amount to have that badge removed.
Considering that this forum gives multiple chances to AI spammers before banning them (I had a case where I reported about 40 such posts over a long period of time before the user was permanently banned), I think that any badge makes no sense.
The case you've mentioned is exactly why I'm suggesting this because most of the time, when we report posts for being AI-generated, the posts get removed, but the users roam around with no repercussions for their actions. So, if mods give them so many chances, give them a badge, which should at least mark them as AI spammers until a point reaches where they get banned.
This is a waste of time in my opinion, and members in Bitcointalk forum can easily get banned for doing any kind of AI generated posts, unlike in other forums.
Chances are higher if multiple posts from AI spammers get reported by other members, than moderators can delete those posts or ban members.
Only ''title'' they can get is banned.
If banning of AI-generated posters become more common, such a thing wouldn't be necessary, of course.

Whatever method we come up with doesn’t fully solve the problem. Humanizers are becoming an increasingly bigger problem. I believe post quality should play a bigger factor when managers decide who to accept into campaigns. It seems that anybody that can do the bare minimum to write a few passably human posts in the gambling discussion boards will have no problem getting hired regardless if they never earn merits and are just shitposting their way through each week.
Even though I didn't mention it in the OP, a badge/title would make it easier for managers to identify AI spammers, it will save them some time because then they wouldn't have to go through their profiles, their trust pages, and whatnot, only to find out what they are guilty of.
And, if you are referring to signature campaigns here, I wouldn't agree because most signature campaign managers are pretty strict these days with their selections and making a few generic posts in sections such as the gambling discussion doesn't get you hired anymore. Bounty campaigns are a different thing, though.
