I've never seen any really obvious bots here like I did in WoW. There, you'd have ones that get stuck for 10 seconds sliding around the same tree every time they hit it in their loop. or make a hard 90-degree turn at the same point every time.
I had one that was killing mobs for skins, and it mounted up every time to move to the next target.
If I pulled one of it's mobs away after it aggroed it, and hexed it (60 second CC) some distance from the bot, it kept him in combat and unable to mount, so he just stood there jumping. Eventually, it's owner would come back, say ??? a few times, then log off. I reported them with a full description of their path glitches, and they eventually disappeared.
