I currently own and run a Facebook application that has 5000 active monthly users, more people signing up every day and about 1000 people use it every day. I used to have adsense on the app until my account was banned (still trying to get that fixed) and adsense used to bring me a good sum per month in revenue. Since then I have found zero way to monetize the traffic or the users. I've tried affiliate schemes like peerfly but their offers don't seem to be appropriate to my users.
What options do I have?
