I totally agree with this, but not because of the horror stuff on itch, but rather because of the "alternative stuff" that could be found in the "Adult" category.
Of course censorship is evil and diversity is good.
But itch has reached a point of popularity, when it has just too many games, and too many different kinds of people posting totally random games on it, so for the shake of peace and happiness of every member of the community, there must be some kind of options to the users to optionally filter out content, or a decent age rating system, or at least some more well-defined principles and guidelines about what's (not) allowed on the site.
I see that people were repeatedly asking for tag exclusions, tag filters, filter options and similar functionality for at least five years long, and it just got continuously ignored. Really, at least people deserve to get an answer about what's going on in the head of itch management about the reason of ignoring the problem.
