I think Brazzers create this rules after Dana Dearmond complained about a pornstarpunishment scene that she got a few bruises. IMO, a few scenes of PSP were good rough sex, others were not rough, but was more to ****. Like the Diamond Foxx scene with James Deen were she play a lesbian (I thought that was a kind ofo homophobic) and other scene with James Deen and Diana Prince. Btw, James Deen posted in his blog that he wouldn't shot for PSP anymore because he didn't like to look like a ******.
Now on topic, that DP scene of Shyla looks like hot. Too bad they ******... It didn't seems to be PSP style.
