What bother me the most in itch.io are some people trying to scam the public into buying something they made without any effort and knowing it, usually because they count that the tool they used is either oldfashion and/or discontinued or simply underground (usually they grab the tool and make something in 5-10 minutes based on demo project or something similar).
I'm not talking about beginners learning game dev. and releasing tiny games and even charging for them (these are ok), I'm talking about people knowingly trying to sell something made without any effort or intrinsic value (if they were for free, then I'd see no problem). There should be an easier way to report these game/assets
