Best cpa for myspace?

Im still having a hard time figuring out what to use for this niche. I dont want to use a cam or dating site because its obviously bs. I have a girls page with alot of guys slobbering over her, what offers could i use to keep them interested and maybe fill out more later?

Im not sure on how to make a incentive site and if i did it would probably just be a bs site.

Suggestions really appreciated.
