Bahh. Porn.. Not a problem making money on it if you know what to do..
That and gambling is the easy ones. You just have to know how to market yourself...
I know a couple of guys who were in the adult business earlier. Gave them a good amount of money... Without any real investment..
The only issue is to get the payment if you have a pay2"play" site..
And FRAUD is a real big issue if you have a pay2"play" site....
For example 2checkout.com does not allow adult sites to use their services...
But i know of a few sites on the net who actually gets you evrything except the domain... Pictures, Videos, PaymentProccessers.. But that goes with you getting a percentage of each signup..
Hmm. This is getting OT.
