I saw profiles of 2 people (one guy and one woman) that I know in real life. Both lie (extremely) about their age.
The guy I know because I met him through Jdate 5 years ago. He claimed then to be 35, and he looked at least 45. A few days ago I stumbled upon his profile, and saw he's 34.
The girl I know through friends, she took off 5 years of her real age.

I reported these concerns to Jdate - no response whatsoever.

These are not the only discrepencies that I found. There's this guy I know who is constantly "between jobs" (or really, just unemployed), and he goes on and on on his profile about his job, how much money he's making etc.

If I needed a dating service, I would not use a service that is told its members lie on their profiles and do nothing about it. Also, it seems that many people lie, and there's really no way of finding out, unless you know that person.
Scary.
