Greetings!
Me and my friend was lvling up in Coldarra and dude namedd Hornymmer (80lvl rogue horde) and his buddies killed us 10-15 times...
Try to write ban appeal but "the selected ban is not valid" was the problem! Have a great day! (not like ours)
I guess this guy was trying to use "Ban Appeal" to report those lvl 80 players.
So, @smouky999:
1. Killing low level players is NOT bannable.
2. You need to open a ticket in-game to report players. More info here: http://forum.warmane.com/showthread.php?t=325598
3. "Ban appeal" is to remove a ban from your account in case you got banned but you did not deserve it.
