If you come across player in a lobby spamming the screen, with a messagage: So and So has been infected by ( internet site) but team HCD, LEAVE! These players can infect your account and cause your rank to reset and have negative stats. Most think it's just them hacking and spamming, but it's causing other players that come into lobbies with them to also get infected.
Edit- Most of the people I see spamming these messages have the clan tag {@@}. If you see these clan members in your lobby, I suggest you leave.
