I'm actually surprised Tinder and co haven't started selling an option to bid money to have your profile be seen first in your city. Same as any other real time bidding in advertising. Have users try to outbid each other to be within first x swipes in the city, instead of "potential match in position 10574" that nobody will ever swipe to.
I realize it might mess with their products' Aha! Moment of seeing only super attractive members within your first few minutes of the user journey, but there's likely a ton of money in it, and a way to strike a healthy balance. I know I would probably end up using something like that.
On an unrelated note, seeding your app with "fake users" siphoned from your peer companies sucks if you're charging for the service. You end up having your users spend hours swiping or paying money to connect with fake profiles. Can't be ethical.
