Well since your asking for spam...
GoForLiveCam They pay you a percent of what they charge per min to the surfer, so if you get traffic that's dumb and will chat for hours you gonna make cash.
CamWhores Not the best payout, but I've gotten nice ratio's with them.
CamGirlsWorld Converts ok, isn't overused like clickcash.
Give em a try, I've used them and they've all had lower ratio's than what your getting now.
