The site is clearly for anyone over 18 years of age as it's a dating site for Christians, but it does not contain adult material, so I'm not sure why other users have marked it as so. I found the site easy to use and although it doesn't have as many members as other sites, most seem to be genuine Christians.
The site is run by Christians and has been around since 2004 (see Wikipedia). As a member I found that most other members are genuine Christians and the database is not shared with any other site.
