I think a huge issue plaguing scripters/bot developers right now is that they are trying to make things look like human interaction. You guys need to realize we're not trying to fool humans, but instead programs designed to pinpoint specific things they are programmed to monitor.
For example, let's say we gained access to Jagex's bot detection program and saw that it only monitored how many times you right clicked vs how many times you left clicked. Depending on the ratio it would flag an account if it became to far unbalanced. Now think, would things like mouse pathing algorithms, random mouse movements, camera changes, etc. matter at all when it comes to ban rates? NO! You could literally create a script that has a mouse move in a linear line towards the target, or hell even just generate an event at the point you want, without ever receiving a ban.
Supposing the above is true, Jagex only decide to monitor the ratio between right and left clicks, if I design a script with a chance of right clicking calculated like this
if (random(11) > 5) rightClick();
it may appear to a human as random but would throw up instant flags to the bot monitor.
My point is that antiban should be created at the code level, not based on how it looks when running.
EDIT: I don't think you fully understood the code I posted or you wouldn't be saying grabbing the closest tile to you is unintelligent.
