What is to stop someone from saying they are interested (when they really aren't) and instead take your creepy digital advances after finding out your identity

What is to stop someone from saying they are interested (when they really aren't) and instead take your creepy digital advances after finding out your identity and publish them on their FB wall for "teh lolz"? Seems like it could backfire pretty terribly for people using this. I'm sure it could actually work too. Though not for me, it's definitely an interesting idea. I agree that the "How it works" page is very immature and could probably turn some potential users off from the concept.
