That is a good question. i have been making a search on google on a good AD company. i know of AdChoice but i can not really get there website detail when i google it. if anybody know any better Ad company. they can kindly assist.

I heard plugrush works wonders. They have a non adult version. 

Another question. Do they pay world wide. No accepting only PayPal as their mode of payment because some country do not allow to accept PayPal as their payment gateway
