"Sanction" usually means "permanently banned". When you are doing something that is blatantly against the RPG Site's Constitution, you get warned formally, i.e. you get told explicitly that if you keep with whatever shit you're doing you're going to get the axe and should knock it off once and for all. If you persist, you're banned. There are no temporary bans and no half-measures on the RPG Site. Either you're in, or you're out. When you're out, you're out for good.
