Thanks for the clarification. That makes sense. So users are the ones that create new tags, without any restrictions for now.
However, my original question goes a bit deeper than just addressing the technicality of how tags are created. Rather, I meant to emphasize the why certain games under certain tags are allowed.
Just to be clear, on itch.io's Terms of Service, specifically under section 3 (Acceptable Use) it states that "Prohibited actions include but are not limited to: posting content that promotes or participates in racial intolerance, sexism..." (among others). If one looks up the definition of sexism (Wikipedia link), it is quite clear that << objectifying women and portraying them in submissive roles reduces women to mere tools, and is a form of sex discrimination>>. By allowing certain games to promote sexual abuse (rape included) and sexual objectification as their main content, are we not allowing sexism and thus violating the Terms of Service?
If that is not the case, I would like to know what constitutes sexism and sexual discrimination according to Itch.io. Just so that I know if I'm only wasting my time by trying to report here games that are inappropriate.
I think we can agree that rules only have meaning if they are enforced. Otherwise, they are useless.
