^Right(After that edit.
It is very possible for a human to click in the same spot EXACTLY for hours. You can either set up a key on your keyboard to click or use a laptop. Both of these have been used in RS for a long time. Now. This makes it so that RS can not tell the difference between a human and a bot. However, human's a behavior changes over time. This change can be easier put into a auto clicker but it would require knowing how the clicks change over time. This can be done with a simple program that most anyone could make that would log clicks and such so that someone could make a bot that more correctly simulated human clicks. This really does not matter, however because they can detect when a random or something comes. So... Get any semi decent auto clicker and watch it like a hawk and you won't be banned. >_>.
