And what if they're not AFK yet simply refusing to play?
Had this in an lowbie-AH a few days back. A Marauder, after one death, went to sit under the spawn (the tunnel with the speed buff). He was hiding in a corner so he was hard to spot. After I called him out and initiated the vote, he just said something smart-a-s-s-y in the ops-chat, went to die in a combat, and after rez he just returned to the same spot.
