I kid you not, I join a server that is playing Basrah, spawn as Insurgent, and then my cell phone rings. I go prone in a field, to avoid being seen, and then walk out of the room with my phone. I come back 5 minutes later and it says "You have been kicked from the server yadda yadda yadda." So I think "Okay, it was just an AFK kick, I'll just join back in." I go to rejoin the server and it says I am BANNED.
:d rillserg
When server licenses are given out, servers should have to agree to some sort of fairness doctrine, which would include not BANNING people for being AFK.
