Is there any different earning between clean ads (Safe for all ages) and adult ads (Adult Content), I mean when i create link, it give me choose "Landing Page Content is:", so which pay more?

Linkbucks rarely pays out many users have complained that it is a scam and from my personal experience there has been no pay out. I would recommend Adf.ly if you want to try a link through cash service - I've heard they pay out but not yet tested it myself.

You would almost be better hosting your own link through script and placing your own ads on it.

I received a total of 16$ untill now...Linkbucks is not a scam for sure...and the payment is instantly when you reach the minimun of 5$, i like them
