How to boost your popularity on OkCupid using CSRF and a JSON type confusion
I have no idea if OkCupid still does this, but they used to segment their users based on attractiveness ratings. At first, I think it was solely just literally your attractiveness rating. They had a feature where you could rate people 1-5 stars and if you were in the top 50% of all rated users, you'd only see other people in the top 50% in your search results. If you were lower 50%, you'd only see people in the lower 50%. I think they eventually made this more sophisticated by augmenting the explicit average star rating with other measures of engagement like how often people saved your profile, how many messages you received, and the rate at which your own messages were answered.Something like this could have been valuable to get you into the upper tier.
