I think you missed the obvious point that this entire issue is regarding those who do come on advertising or leading others on as if they are trying to meet others.
Those of us, such as you and myself, that only come here to take part in discussion are not a problem in this regard and don't need to verify that we are what we say we are .
However, it is a big issue for those that take the time to respond to others in the hopes of actually meeting and then get strung along not knowing if the person is really sincere or just fucking with them because, instead of being the hot white wife looking for BBC or the black stud with a BBC, they are really some old, fat white guy posing just to get attention.
Even worse is when they take the time to travel to meet someone and get a no show.
The photos of a nude female body or black guy holding a sign in front of their face with their "handle" and date would help them know that at least they are really corresponding with a woman or black guy. Still wouldn't guarantee they would actually meet though.
