Because I've been banned simply from posting too much information about my account. I know this for a fact because I know the exact J Mod who did it. I'm friends with a few P Mods and that J Mod had a big mouth and was bragging about my ban. In fact, the P Mod I'm referring to knew I was banned before I did, and I found out first from him, before I had even tried logging in that day. To be straight, Jagex's ICU knows me by name and spent over a year trying to catch me; it was my carelessness with information that lead to my ban, not being caught botting.
