This is either fake, or the jagex moderates have been watching there actions, they can't just say "OK, level-3 picking flax, or woodcutting, default-look, ugly name, *banstick*" So i'm guessing this could be fake. There detection system is far advanced, I dont work for jagex so I cant be sure how good it is, but I bet it keeps trace of your mouse-clicks, time intervals(on actions your doing) and other stuff. You know if you use a autoclick to "CLICK" the same coordination's everytime they know this, and if you do if over and over, you will be banned. It's really hard to beat the system.
