To be completely honest, with the way popular bots work nowadays it's extremely hard to tell.
Simple youtube videos showcase more advanced, randomized mesh pathing as well as plugins for proper rotations, movement, dodging, etc.
We need to really rely on SE rather than our own suspicions.
These botters are not smart, they are business men believe it or not. So they are going to have that bot running until their PC gets so hot that it turns into a spaceship and enters atmosphere. SE just needs live GM spectators in areas with activity.
