Bonnie Rotten looks a lot better with long "normal" hair. Though the fact she's made such a career after having those tattoos is somewhat remarkable, usually it's later you start getting horribly misjudged tattoos after the bolt-ons and start sending your career downhill. Though there seem to be more bad tattoos in general on new girls lately just from a casual glance at sites/videos. Big gaudy thigh ones that are like a splotch and go nowhere are like one of the few ways to actually offend me in porn.
However.
Worst tattoo in porn is still that guy who has tweety bird on his abdomen.
