We review all signups and their submitted content, and we have a fake account type "AI creator" which we record, so if they tried that first, it's a clue. We also integrate a third-party AI detection tool that checks their uploaded content before they get access to the community, and we use a second third-party tool as a double-check, and if we still doubt ourselves, we'll ask for their workings-outs in some way that is relevant to their creative type. We also ask them to prove they are the author of their work through various time-tested mechanisms. I have no idea why people do the things they do. People are a mystery to me.
