I liken these adult dating sites as similar to Skokka and Locanto. There are some genuine ones out there, but way too much bullshit to take them seriously. On Facebook, I keep seeing adult dating sites advertised. They have one for Over 50s, and the girl they use in the picture looks about 25, very attractive, and they expect you to believe she's available. Her mum wouldn't be over 50!!!
There was one who the boys on Facebook had fun with, the same woman, different name, different age. They want you to think there are stunningly attractive women out there who have trouble getting a man. Absolute Disneyland. I wouldn't trust these sites as far as I could kick them.
I recall trying one once out of curiosity. Just like Skokka, completely different person to the one in the profile, different likes, interests, you name it. Why waste everyone's time with this rubbish?
