I agree with @[email protected] , that you're likely to have a lot of bots and fake profiles ... and it's likely to turn into a platform for soliciting prostitution.

However, I think bots and fake profiles can be dealt with in various ways. First, captchas, second, a very easy way to signal that the profile is fake or a bot

like three buttons: like, not like and bot.

Another way to increase moderation is to allow some extra privileges (for a limited time) in exchange for moderation services. Extra privileges might be: extra "super likes," increased range, being "featured," ability to send a message without first liking, ability to hide location, etc.

Moderation would basically involve looking at a profile and determining whether it was appropriate or not (clearly these would mostly be profiles that had already been flagged ... but perhaps not enough to warrant removal yet). This might be just looking at the profile and determining whether and what kind of inappropriate profile it is. This might be an anonymous chat between the suspect profile and the moderator. This might be asking the user to assume a certain pose, allowing them to block their face with a T shape and then having the moderator determine if they assumed the correct pose.
