I wonder what your definition of “reputable AI checker” is? To date, I personally have not met an AI checker that I would call authoritative. Absolutely all AI checkers have one or another error in AI text detection. Although I have one AI checker that I trust the most.
All of them I tried have flaws and they make huge mistakes, but combination of several tools gives lower margin of error, and some common sense is always needed in the end.I wondered, what do you say about this topic [ANN][IDO] RGames [RGAME]: Revolutionizing Racing - Develop, Play, and Earn!? Do you think there are a lot of posts in this topic written by AI? Only without verification 
I am not sure if all of them are AI generated, but this topic is full of crap written by newbies that are all probably controlled by one farm, same generic account names, posts generated in same style that creates fake conversation.I don't visit jungle of altcoins section in forum so often but someone really needs to start reporting posts like this.
