Well, yes, for porn, it'd make sense,
But for Porn, if you show up with an 11-inch zucchini, a desire to be filmed using it, and can pass the screen test, they're not going to ask for your license to see if it says M, F, or X.
A few years back, the porn HR department would have wanted to see it, to know if you got paid on the M or F pay scale. And to know if they could pay you porn money directly or if your husband needed to know about the porn money. But that's at least nominally supposed to have expired, thanx RBG.
So even pornjob scenario doesn't justify that block on the card....
