Correct me if I am wrong, I have came across where the said poster made a reply to either any of these #2 and #3 saying that he also tried to check their post and the AI detector detects their post to be AI generated, although I don't know how true is this. But I will also like us to check your personal post to know if the AI detector could still give you same result, this is a tools developed by human like you & I and there is no guaranteed that this tools is giving you an absolute results apart from give a guess feedback whereby people would start painting someone profile as red or giving them neutral tags for a common mistake done by the tools issuing out random results.

I think to me the one that should be more effective on members should be a copy and paste content without any link linked to the original author maybe if someone continue to repeat this kind of post without referencing the original creator or author then you can as well tag such person as a plagiarism user who does not make or create it's own original content than stealing someone else as his personal post. However, I am not against anyone doing his find on those that uses AI to post but we should also try to check most of our personal post to see the results if it appears the same then we can say the tools is giving a random answer to people's post, though I hardly use those tools to detects people post.
