Seems degrading to me, so no I wouldn't use it. People who are dying to pass putting up a hopeful picture only to have a bunch of cisgender ->-bleeped-<-s come along and say no (because we all know it would happen regardless of supposed exclusivity and regardless of level of passing or not). And even if we managed to keep it exclusive, I'm not sure a site dedicated to judging people on their appearance would go well for a demographic of people with a 41% suicide rate when a huge portion of us put so much into our appearances.
