I joined after seeing an ad on TV because I wanted to see what sorts of people were on there.
I discovered that there are few to no real people at all.
I get one message per day, at about the same time, from a person who usually has no photo, and a profile with zero to 10 words in it. Obvious fakes.
I can't read the messages because I haven't paid for a subscription. I'm sure they are nearly empty, just sent to make me pay to see them.
Just to add, I have been on multiple free dating sites and usually get one message every few months. It is beyond obvious that one message a day is total BS.
