If it is just to correct your sentences or what you are about to post, not bad to use AI
For me it's bad using AI to correct a sentence, before existence of AI many people used their brain to compose articles, anyone who intend to use AI to correct it's sentence will no longer be comfortable with he or her sentence, since using AI is prohibited I think the best thing to do is to stay away of it, anyone who calm down to write, will make a good sense, the issues is that so many persons doesn't review their sentence before posting, and they do ignore the review button
There are some hand written comments that look like AI but it's not, these comments do not engage in the discussion but summaries a topic which is not actually good, if you are the type that post like this then you have to stop posting that way because it seems to be AI written note.
It's won't be accurate like AI written, the accuracy of hand written text and AI can't be compared, there's a lot of difference when you come across of them, especially if the person started using AI newly, just compared the old post of the person and new post, no matter the improvement in post you most detect it's a hand written
That said, the forum never get any rule against that though, because e dey hard to prove completely that a post is AI generated, there would always be false positives, so mods no dey really ban people for AI generated posts. The thing be say, forum users go tag your account with neutral if you are suspected to be an AI spammer and no campaign manager go wan hire such a user.
I know that there's no rules and regulations in forum that relate with AI generated text, but forum is against it, when mods noticed that you are using Al to compose a text, they doesn't react immediately, such user will be under their watch until the evidence is clean, and will decide to give the person signature ban or temporarily ban, why other forum members may decide to give the person neutral with a strong comment that will signature managers to ignore the persons applications.
