Look at this newsarticle (Dutch):
nu.***nl***/news/769679/57/%27Pornospam_meest_succesvol%27***.***html
That's some wicked high conversion for spam 
 
 
It says that 5,8% clicks on the url in the pornspam. Now I got wondering are there then affilate programs that do allow spam? Because they must get paid someway??? 
 
 
So, wondering if anyone can clear me up on these people. Maybe some interview on some site? Like they had @ wired with the spyware dude's etc.
