Need Some Ideas

I joined up with this pretty cool randomizer, which i know the payouts will be allot better with more traffic because it's pretty new. I'm already doing ok.I very greatly respect everyones opinions at blackhat world. Does anyone have any ideas for traffic generations like some safe-lists to join that have a good return? I don't want to spam anyone but i might consider double-optin safe lists. Anyone have ideas other that ppc?
