I recently found a game (locked) that had 4 ppl and it said lvl was 66. I tried a few basic passwords then i got in. It was 4 lvl 66s. A bear, a mage, and two birds (a good group). I sopke but no one responded. I finally caught up with them and they moved in the same exact pattern and all moved at the exact same time and were from the same guild. I stayed with them for a few games to leech xp and steal drops . I then decided to do something evil. They were hugging the wall to avoid a boss and i just went in and aggroed the boss and it killed all of them. That is how i killed the botters!
EDIT: I got on again today to see if i could get them killed again but they were not on. I hope support took care of them.
