I signed my mother up, as she has difficulty meeting men her age (60-65) in her rural area. This site is a hunting ground for scammers. She became involved in 3... count them... 3 men in a matter of 3 months. Each and every one was a scammer who eventually (some sooner than others) made the "request" of financial assistance or goods. All 3 had phone numbers that were suspect. All 3 declared their love within a week or two of chatting online. The first one stuck around the longest. My mother did not lose any money, thanks to my supervision, but she did text pics. I'm sure they will be used to impersonate a fake profile to scam others.
As if this wasn't enough, the credit card I used was hacked and a whole bunch of charges were made for Match and two other dating sites. One site made 9 $50 charges in one week! There is only one reason I can think of... paying for a pile of memberships... to scam people. Surprise, surprise.
These sites are infested with the worst the human race has to offer... people who are trying to take advantage (of the elderly, in particular). If there is anyone "real" you'd never find them. Back when I used dating sites, the worse you had to worry about was people misrepresenting themselves (mostly age and physical appearance) to try to get their foot in the door. Now it's a den of thieves.
