Basically the ghosts in the screenshots are the bots.
First Screenshot
They both stand in the same location and never move out of the location. GPRS was using a club and just hitting. He stops when mobs are dead.
JDM_Toyota_Ae84 was an archer. Just stood there and kept shooting.
Then both died for no reason and their status became away for hours.
(Some people I saw came back for a few hours later, resurrect themselves and kept repeating). They are usually on team with auto invite even they are dead.
