@Mad-Kruger, I do believe that this, being a porn site, provides you with the tools needed to not waste your time on content that you dislike.
I believe that you would want use tag flagging to flag galleries with the tag "male:yaoi". That should eliminate most of what you've decided to dislike from needing your scrutiny.
Though, perhaps you could use practically any other word than that one, being a word with a particularly nasty history of hatred.
