It doesn't really affect me. The only times I ever use PF I'm specifically looking by filtering. I never look at "all" so I never even see these adverts.

For those saying SE needs to do more, you need to look into studying some law. They aren't breaking any rules and thus banning them opens SE up to lawsuits stripping them of cash we need to improve/expand the game.

Honestly, Blacklisting should simply prevent them from showing in your PF. I am honestly surprised it doesn't.
