Personally, I would be very wary of any adult talking to my daughter on the net.
If it was my son I wouldn't feel so bad about it but if I had a daughter I wouuldn't want her speaking to older guys if she's under 16.
I know the way the net works* so I would have a hard time trusting them.
*For example, my ex (who is now one of my best mates) gets hassled non-stop about the fact that she's female every time she plays Ghost Recon or Call of Duty online by stupid male geeks who can't get a real girlfriend.
"You're a girl??? Got a pic?" Losers...
