will my alching be detected?

Alching at pc bank is the best IMO. I usually high alch in pc-themed worlds. Although it has more people, most of them bother to do their own stuff like withdrawing other eqs for pc games or trading. If you're on a low people world, a few people might ask you and talk to you. Crowded world is better IMO. Might be wrong though. Psychological advantage. =D

 

Go to Void Outpost for no randoms and use an autoclicker and set it up so that you always keep clicking and don't have to move the mouse. If you use a highly populated world, then you will be hidden among all of the people, but sometimes you can get caught.
