When you're banned on this forum you either:
A) Fucked up so many times that your infractions reached the ban limit, which is entirely your fault and your fault only.
B) Fucked up so bad you were insta-banned. When this happens, it's because you did something so incredibly stupid you'd have to be brainless if you didn't consider it might have consequences, thus making it entirely your fault.

And seeing as how this is probably about someone (you?) being perm-banned, it's likely a combination of A and B...
