It's the sort of thing that seems like it would be easy to create unsubstantiated rumors about - especially since it's both the sort of thing that's been falsely claimed for marketing purposes (see, for example, Noname Jane's cameo at the start of 5 Guy Creampie 30) and the sort of thing anti-porn crusaders use to stir up moral panic. And, I think, the sort of thing that nobody involved is actually happy about when it does happen.
