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
Do you know about Grammarly tool? It is completely AI controlled. It is not used to make posts but rather coordinates writing errors, like right punctuation, preferred choice of words to fit in the sentence, also helps with spelling and so many other things. Don't forget that not all Nigerians are fluent in English, some of us are more native speakers than English, despite pidgin being our popular language.
The rule of using AI in the forum is don't copy and paste from AI, make your inquiries, understand the concept of what you want to discuss, and in your understanding give your reply. Yes, AI also has its disadvantages, so you also have a point saying what you want against the usage.
