1. Get an editor to rework the copy and fix mistakes. There's a lot of phrases that are almost-but-not-quite correct, such as "safe friendly trust" (which is the first thing that people see)...You don't want people's mental spam-alerts to go off at first glance. A lot of the text is also awkward and slows down reading (avoid using the forward-slash...e.g. use "attractive" instead of "cute/handsome"
2. I didn't want to give access to FB to use the site so I don't know how it works other than the landing page...but is the only way to express interest is through calling someone "cute" or "handsome"? Other sites have used "I'm interested" as a way to express...well, interest.
3. Try to replace that stock photo with something unique when you can...and if you have to use a stock photo, don't use one of all white people, unless that's specifically the audience you're catering to.
4. Also, don't describe your users as "boys and girls" unless that's specifically the audience you're catering to.
5. Cut as many adjectives as you can out of the copy, it doesn't engender trust. Also, don't use the word "disciplined"...it doesn't have useful connotations in this context.
edit: After reading the About page, I have a couple more things to add:
6. There are so many reasons why people have negative feelings about traditional dating sites and you can't possibly enumerate all of them...so minimize the amount of telling people those reasons, as you make too many assumptions as is.
7. Related to that: there may be situations in which the phrase "call girls or prostitutes" is applicable, but the promotional copy for your positive online dating website is not one of them -- in any context.
