I go by
rule #1:
Post nothing until the deal is done.
If I was a scammer your are damn right I would be off checking all the other sites.
Rule #2.
The pics just don't count , I believe it to be rare that they would be using thier own pics and alot of it is run by mafia types. So babe_in_rusland is correct that most are stolen from somewhere. Now that is a bummer cause I have seen some very beuatiful women.
Rule #3.
Always be prepared , you want to play the game then get some accounts with different names. Get different email accounts. Get a postal box.
Never give out your real info
