If it is your contention that these actors are digging an early grave, that is highly unlikely. These are people with nothing to lose and much to gain by their notoriety. Yes, eventually their status will fade, but not because their actions caused them to be shunned by society, it will be because society grew bored with them or simply forgot (no longer cared) who they were. These guys want to work, so they draw attention to themselves. The more noise they make, the more opportunity to make more money.
Looking at madonna, her album debuted at no.1 after much was said and done to draw attention to herself. Now, 3 weeks later, the thrill is gone and the album is at no. 15.
