My friend and I got tired of looking for a game that wasn't full, so we finally made one. We got stuck with two players on our team who started TKing us and fussing at us the whole time. There's no way to report people like this and no way to votekick them. The frustrating multiplayer experience makes me upset I wasted money on L4D2. There should be at least a mechanic to sense people repeatedly team killing.
