Welcome to reality. Porn performers aren't making scores of thousands per scene because 99% of the people want to watch porn for free. The condescending attitude from readers of these articles who then go to tubes and enjoy their fap is really outrageous. Pay for your porn and maybe performers will be making more money. How's that?
As to Khalifa, there was a really nice op-ed article on xbiz on how much of a victim she was, and I'm going to link to it as GFY is no longer part of AVN :D
