While i would like more choices in badges, it wouldn't take long before, people started in with the penis, goatsie, nazi, etc., badges.
Even some benign badges like your companies logo, or countries flag, could really ruin the game.
I get that it's "regular players" only, but as a person that runs a few games servers, I can tell you, it's not just new players that make poor profile choices. Well established, and some times well meaning, players can make some pretty offensive choices. Specially in a context that spans several countries.(i.e. we don't all have the same idea of offensive)
