About 99% of the networks everyone else listed are complete jokes. If you're looking for a legitimate network that offers paypal payments, you're going to have a tough time. However, one I know of is Affiliate.com (formerly CPAEmpire). You have to fill out a special form to set up paypal payments but they're happy to provide you with it. As far as adult, no, they don't have any adult offers, other than "adult" dating type offers.
