When it happens to you as a provider, you might understand why some are not that stupid. Again, just skip over the providers who don't show their face. Don't expect them to change for you regardless of whether or not you are screened. Many guys get screened for an atf just to fk with other providers. I know women who had their face shots sent to area hotels in an attempt to have them busted. When you know how severe these things get, you might be able to offer advice on what providers "should do."
Have you ever heard of eccieleaks? Nuff said.
As for a face pic with big sunglasses...I have that on my damn site lol. You still can't tell what a person looks like through sunglasses, so what's the point?
