Yes, I can see your point of pedophiles targeting on people they know their young by age, but if the pedophile is really out to get someone they will find a way, although ussualy they will just go to myspace and find a target there, I think it's very unlikely they will go here to find a target, but I'm happy to see you take steps that incase they do that it's as prevented as possible.
I'll go see if I can find those topics
I thought they were probably removed because of this rule.
