My app idea. How to monetize?

I'm calling it Beat The Pedos. It uses a social networking to catalogue all the freaks in the user's area and schedules beatings for them. For example, of one particular pedo has gone a month without being attacked, it finds five or six users that have some free time and sends them to pay the sick fuck a visit. Rough them up a little, smash their 2hu dolls - it keeps them in line.

Obviously, I'm making it as a public service sort of thing, but it would be nice to be rewarded for all my hard work. Still, I'll be honest and admit that there is obviously very little chance of any reputable ad network putting ads here, and if I charge money then I might not reach enough people. Any ideas on how to monetize?

You could charge a fee for getting delisted (on a subscription basis)

Maybe they could install the app and they would get a pop-up "whoops, looks like tomorrow is a beatnsday", and they could pay a little something to schedule the old ultraviolence for next week instead.

All handled smoothly as an in-app purchase.
