I'm fairly new here and I'd like to use it more, but, there are a variety of general categories of communities that I'd like to never see. So instead of blocking them 1 by 1 as they pop up I'd like to have the ability to say "Block all communities that are sports related" for instance.

I realize the alternative is to look only at the ones you subscribe to but then how do you discover other communities that were just created without flipping back to Show Me Everything?
