Unfortuantly, I was unable to get a Steam ID because he DCed immediatly after his latest TK spree but this guy today on ZM factory and LostWorldRedux was Zteleing from zombies, breaking down cades, and about three rounds after Walter left the server, TKed about a dozen humans on Lost World by blowing the bridge on them with no zombies in sight. So I'll just drop this off here as a heads up on a troublemaker, until I can get a proper SteamID next time I see him on.
