These sites have many fake profiles submitted by employees, and they take pictures of other highly attractive people, and build too good to be true profiles
Then post them. It is done to give you a false sense hope that these people are real and you may have a chance with them. Try finding a real attractive person, give them a flirt at a unusual hour. 7:00 in the morning, or during the time when most people are sleeping, and see how fast the automatic respose comes back. That is how they hook you. "It's an automatic program!" Also there are Scammers allowed to be on these sites with fake profiles comming from overseas to prey on desperate, and convince them to send personal info, and even money. For a plane ticket, or even to help them with a dying child who needs money for a kidney.
"BULL CRAP!" If you use these sites always get to know where the local profiles are comming from, and ask what part of town they live on, or quiz them on locations. And be aware of bad grammer, or answers that don't make sense to to your questions."SCAMMER!" And one more thing. Would a really attractive person that looks as if they could pass for a model, and have a masters degree, no children, never been married, age 30. Be on a dating site. Hmmm "BULLLL CRAP!"
