I think that we should post whether or not we accept criticism on our profiles, and if someone feels compelled to comment they should check there first. I don't mind constructive criticism myself, but we live in a world with different types of people. Say a person has a disability, and is truly doing the best they can. Is it really our place to criticize their work? Is it necessary? I've seen some models that have flaws in some areas but are killer in others. No one is perfect, and not everyone wants to be. Just sayin'.
