Yep. I think it's a 14-year window they allow? I set my age to 34 so I could talk to 20 y/o girls.
The one hot girl I know with a pof account keeps hers hidden, so only guys she messages can see her profile. Otherwise she gets 100 messages a day, but they are all like 'hey wassup u hot u dtf?' That's the gaming skill of your typical guy on pof.
Assuming that is her only pic, I'd message the girl with the tree tattoo, which is a "tree of life" tat by the way. Girls with no pics of themselves are either hideous or hot. You're not going to find out until you talk to her.
