people have more chance to dont get banned if they keep playing than d/c
they are stupid, when you d/c its the biggest proof that you were botting
when you stay loged on, gms may have some troubles and doupt, and you have better chances to dont get a ban
and besides, if it was really joyNax he wouldn't be doing anything. He would say "we are working on the bot problem" or some such carefully worded excuse, then go back to counting the money the bot players are giving them.
