Paul Barresi (born 1949) is an American former pornographic actor, former pornographic film director, and media personality. (wikipedia)
He would dig up dirt on any celebrity who might be a potential client. Then he would tell the celebrities about the bad news floating around, and he'd get them to hire him for protection.
He felt that he was untouchable. And he also probably felt protected.
He may very well have wanted the dirt to use against Stallone. Maybe Stallone crossed him. I don't know. But I never asked questions.
