I use a wired Xbox 360 controller and my left stick sometimes sticks so when i'm afk my character wanders aimlessly in a circle. I wouldn't say this is a bot.

This happens to me all the time, and I also use an xbox controller. I'll go get a drink, come back and be walking like an idiot into a wall somewhere.
