The only two on the list who qualify for slut status are Sasha and Tory. I can't help but think that Sasha Grey's sluttiness wasn't as much a part of her as it would seem. I bet there are some scenes she did that she wouldn't argue with you if you were going to wipe out all the evidence they existed
Tory always seemed completely invested in and completely enjoyed being a a nasty degenerate slut. I think if you tried to make anything she did on film disappear she would be pissed.
