They can make new settings but it'll be hard to sort the things that are already here. They would need to use AI to decide whether a game had "extreme gore" or "sexual content" because a lot of creators are inactive and won't return to re-tag their older games. (Or they are active, but don't want the hassle of recategorizing a lot of games.)

Using new AI to scan and sort would be the worst option, by far. Have you seen what’s going on? That would only cause trouble.
One of the better options would be to adjust index rankings (existing process with what is likely familiar algorithms). Older works with few or no tags that haven’t been updated in the past two years (as in, less likely to have been reported for rules violations) would sink to the bottom of results, where it would be obvious to anyone looking that more personal discretion is needed.
We’ll always need to do some of the sorting and screening ourselves here. Expecting a site known for subversive projects to have professional curation that exceeds even what we get in national collections would be totally unreasonable.
Besides, the bug that was a major part of this discussion has already been fixed, the Itch.io team has spent the past year going through and assessing games suspected to be violent or contain erotic content, and in my experience, popular projects are pretty well tagged for how varied this site is.
I wish more tags could be used at a time. But that’s a separate request.
