WRITER'S STRIKE: PICKETING FOR PORNO

Now-
This is a legitimate question:
We are on day eight of the WGA writer's strike. But I am curious-what about the porno writers? Are they part of a union? Sure, the scripts aren't exactly stellar. And no, no one watches for the heartfelt, thought provoking, Ingmar Bergman-esque dialogue. But someone has to come up with lines like:

HOT HOUSEWIFE: "But I didn't order a pizza."
BEEFY GUY: "Okay, what about my cock instead?"

Are these people being paid properly? If not, are they picketing some shithole porno studios in the 818 area code?
Are they wearing t-shirts emblazoned with:
"We're The Ones Getting Fucked!"

Are they chanting slogans like:
"No Justice, No Anus! No Justice, No Anus!"

I need answers.
