Another reason for not starting a dating site is that you will need lots of lawyer coverage if a minor registers and you get a call from FBI, Interpol or both of them.
Already seen it happen, and the dude that got the minor registered on his dating site got completely slammed. A site that was making him about 500 euro/month in ads got him 50k euro bill for not policing properly the registered members.
Running a paid dating site completely removes that problem because its supposed that credit card users are not minors... yet I had my first credit card when I was 14 years old
