Yes it is possible but the chance isn't high. Just take care of several things like:
- bot time
- sleep times between interactions
- speed of mouse movement
The input type matters too autoit is using the winapi for there interactions if you want to go 100% savety use a keyboard and mouse driver hook to simulate real hardware key strokes.
The most people get banned cause of huge online time and when they get reported by players and a GM is checking there behavior.
Happy Botting!
