In the FAF lobby it'd be nice to have an option to see what accounts have shared that IP address. Not making the IP visible per se, only what accounts have logged in from that IP address.
It's pretty frustrating to balance a game and find out that some of the players are way more skilled than their rating implies. I'm sure I'm not the only one who's had games ruined by this. Obviously someone could mask their IP but at the very least this would filter out all but the most dedicated smurfs.
