Here's my personal take on this. The girl is one stupid, airhead bitch that will regret all this real, real soon, if she's lucky enough to not be found dead from an OD or found in a dumpster.
The guy who put the tat on her has no feelings for who he screws with. He looks at her as an object to be used for the day and cares nothing about what his actions does to her.
BOTH will screw YOU over in a second, so both types you want to stay far away from. How you conduct biz is no different in porn than on wall street or anywhere else. Some are money hungry with no ethics who destroy everything around them until they crash and burn (and they always do).
Others have ethics and have a line as to what they will and will not do. It may take them longer to get where they want, but they WILL get there, and stay there much longer after the other type rots in jail or gets beat up by people he screwed over.
But what do I know!
