My first method was using lfas.co + CrakRevenue + adult blog.
Lfas is a url shortener "sui generis". It lets you shorten your links while specifying a page you want to advertise (in my case a CrakRevenue CPA offer). In this way, when a user clicks on your shortened links, a sort of popunder with the page you advertised will appear, but it won't be blocked by popup blockers, because it's not really a popunder (I don't know how to explain this...).
Anyway it converted well in my case!
