I think otherwise; probably those who used AI got other tools that humanize texts well, and unfortunately, there are a lot of them. Because of this, the number of those caught decreased. Without expecting it, we taught spammers AI how to write posts so that they are undetectable. Yes, AI is easy for everyone, but there are many tricks on the Internet on how to work with AI and not get caught. I think fans of this tool will definitely use such methods. Those who simply copy texts from the Internet during such technologies as AI, one can say, are at the lowest level of development and laziness, and it is probably not worth expecting that they will be able to extract something from the forum. Although the ban on plagiarism in our time is considered for each person personally.
I just now noticed that you had replied to me. I 100% agree with you, but I believe it's both. There's no way the AI Report Thread doesn't have an impact on AI usage, I kept seeing full copy-pasted AI posts all the time, the number of those posts has dramatically decreased. On the other hand though, I am seeing a few users/posts that look like AI, but aren't detected as such, and you can't accuse them without solid evidence. Certainly, spammers have gone smarter and are trying ways to evade being spotted, it doesn't take much, just a simple Google Search, and numerous results of humanizers and re-writing software will appear.
