I wouldn't even mind if it would be an actual AI, that's posting to learn. But it's shitposters farming accounts posting things they're not interested in and don't even understand.
The only good thing is that chatbot-producers will use more and more of their own data to train their models, which may slow down their improvement. But that also means the internet as we know it is lost.
Meanwhile, I noticed one account who plainly indicated that he was using AI to post here on the forum; I can't recall his username, but I haven't seen him around in a while. But why would someone create an account just to post AI content? I mean, the user wasn't in a signature campaign, so I'm not sure why he was doing it.
We can not eradicate AI chatbots entirely, but severe measures are being executed (case-by-case).
