On the flip side there is AI (to include chatbots) and that is basically taking things too far when it comes to this forum populated and dominated by humans. If those claiming to use AI to correct posts want others to believe them that is a different matter altogether but using AI to generate replies for the sake of trying to build accounts with minimal effort to make money from them is basically not intelligence. Would you agree?
I agree with you that people would only be joining this forum to earn money which is not wrong according to Theymos but still, I think will hurt the main purpose of the forum. Because people would be making fake content, content that would be so obvious, and most of these members wouldn't even be new. Most of them would be alternative accounts.Personally, I welcome intelligence in any form. This forum need all that it can get. 
But I also agree with c10h15N because AI can't be ignored, and whether you agree or not, most of the members on this forum are already using AI chat bots for various tasks. The point is, some are using AI to understand some terms, learn them, and then share there own POV, while some are using it to find scammers (this I found out yesterday), etc., etc I don't think grammatical correction apps would be considered AI but if they, everyone needs to know some official rules. Yesterday I read a post, came from the moderator, he said a person can use AI but has to give the source for it like when we quote some words we use a quote words or give source link, same way a link should be given.
