Possibility to hide all of a specific type of game (i.e. "hentai")

I would really love it if I could hide all games of a specific type. In my case I find myself hiding a ton of hentai games all the time and there just seem to appear new ones all the time.
My suggestion would be, that creators of giveaways could tag their games as "adult" or "hentai" or something like that and that everyone had the possibility to auto hide all games with this tag. Maybe even auto-fetch the tag from steam? Though I'm not sure if that would work. Especially since it's not about hiding anything with "above 18" content. Maybe people have other categories aswell they would like to hide.
