Hey :) am an average gal, few extra pounds etc. Intelligent, sense of humor, 2 kids, single by choice until I meet the right guy. Have met quite a few guys through POF, just not the right one yet... IMO ALL dating sites have an issue with fake accounts - OKCupid, Be2 (the worst!), Tinder, etc.
Have read a lot of comments by disgruntled men here... jeez, try being a woman online dating - have had to learn to report/igore/block many because of totally inappropriate (or just disgusting) requests, but seriously, POF is no worse than any others (no I don't pay either). Some people just leave their accounts up and don't check in, not fake, just inactive & I suspect they leave them there to keep their numbers looking better. Learn to recognise the fake ones - poor English, pushing too fast but never available to meet, time zone differences (late nights/early mornings), request for email address or messaging account instead of mobile phone number to communicate. Ladies and gentlemen, if they do insist on emailing you, research how to get the IP address from the email header, then find the IP address online... it can at least tell you which country they are sending the email from, it is in the packet information in the header of the email (yeah, have a degree in IT... said I was smart!). That skill has saved me wasting my time with scammers already. Have reported them too (with some success).
Just be smart about on-line dating. Keep your expectations realistic and don't try dating on-line if you are desperately lonely... it is not the role of some other person to fill that hole in your life... that's your job!
