I have seen a lot of high-ranked members constantly posting AI-generated posts and their posts are always identical and you can see that they aren't written by a human, what's worst is that they don't even edit them and you can sometimes find sentences and words that give it away that they are using an AI language model to generate those posts.
I wonder how difficult they find it to write posts themselves that they do this, I mean, if you have nothing to contribute, just don't make posts at all, but then again, they need to earn money from here. Signature campaign managers need to up their game identifying and catching AI users.
You may be right with a few though, I can't possibly know everyone and read all posts, but the overemphasizing it is what I do not buy. But if you are sure of this, then you should not keep silent. You should report it at the appropriate sections of the forum, especially if they violate the moral ways of using AIs on this forum. The issue is that there are no vivid spelt rules regarding the use of AIs here, yet there are some plain use of it that would violate the rules of the forum, especially the plagiarism aspect of it.
There is no way one can be using AIs without plagiarising if they do not edit it as alleged, so you can have a valid point if you point us to those posts for us to also judge.
