Block Listed Players

So I was thinking. It's really too much to expect for Riot to maintain player made game modes etc etc. But. What if they made it easier for players to do it themselves? It wouldn't even take that much. You know how a blocked player shows up as such on a normal lobby? Why not having them show up like that in custom lobbies too? It would make it so that if someone trolled around in a custom game, you could blocklist them, and then not have to scour your block list every time someone shows up.

Just my two cents.

P.S. Is this in the right place? It either belongs here or in misc right?
