In that case, the administration should take a position that would be clear, and if everyone (or the majority) shares your opinion, then it should not happen that some members, even after several dozen reported posts do not receive even a temporary ban due to the use of AI. If using AI inappropriately is the same as plagiarism, I guess the punishment should be the same.
I've seen quite a lot of tools wrongly detect a post as AI generated, when it actually isn't. I know you can say it has to pass through several tools before a conclusion can be reached, but if one tool is saying it isn't AI generated and another is saying it is, the accused user has an argument and banning them outrightly might not be possible. Using AI chatbot to post can only attract the same punishment as plagiarism, if it can be completely proven that the post is AI generated without any false positives.
If you were observant, as _BlackStar rightly pointed out, you would see that we use several tools to identify posts written by AI, and only based on their overall output can a person be accused of using a chatbot. Moreover, by checking a huge number of posts, those who use these tools can even determine at a glance whether a person wrote the text himself or not.
Today, there are already tools that give accurate results, and after testing, all other tools also show AI texts. In addition, you can always check the posts of several people for comparison and make sure that all other posts will be identified as written by a person. But messages from a person accused of using AI will still be identified as being written by a bot.
If the forum is indifferent to those who use AI to write posts, then the forum will turn into a place where robots communicate with each other, losing the meaning of communication and humanity.
As children, we often played with dolls and talked to them. Is anyone ready to look like a child talking to a robot while naively thinking that it is a person?
