Forgive if this has been asked before but why is the SSP banned in WWE. Did a wrestler hurt himself doing it or is it because it's to risky to the guy having it done to them. Like to many knees in the face or something? Or did somebody mess it up really, really, really bad like Hayabusa did in his match with Mike Awesome?

Also what other moves are banned? I know the pile driver is and I'm pretty sure Gregory Helmz's cop killer is banned but what else is also banned?

I'm interested to see what isn't allowed anymore or for that matter never was in the first place.
