The second of those liks goes to the default page set by the paysite owner.
If you use the first link it can go to any page you wish.

I hate sending surfers to warning pages, so if its a ccbill account I always send it to the second page. I have never come across the problem Jimmy had as yet but it is a good idea to just watch the clicks are being recorded.
If you want to see how it works more go to
