Prominent figures in the adult film industry are accusing Google of discriminating against their genre.
Google recently started promoting advertisements for legal ways to download music and movies when searched by consumers if they buy advertising.
At this time the online adult industry is not permitted to purchase advertising space on the Google network, which is angering those who are employed in the adult industry.
"Google is perpetuating the misconception that the adult industry is not a legitimate industry," actress Angela White said to BBC. "The adult industry is run like any other professional industry; we pay taxes, create jobs and contribute to the economy."
Google refused to comment on the issue.
Tasha Reign, an actress and studio owner in the industry, told BBC Google is "still treating the adult industry as taboo."
She added that some worries stem to the politicians who are working to enforce tighter rules on online content so it doesn't fall into the hands of children.
Reign pointed out, in defense, that if Google worked with the adult companies Google would be able to be certain that the websites enforce age restriction rules, whereas it's impossible to enforce on pirated sites.
"Society doesn't view sex workers as people, but rather commodities," the president of Girlfriends Films, who is known simply as Moose, said to BBC. "It's a mentality that has to change, not just because of piracy, but for the good of society as a whole. Pirating adult content hurts real people, from the women and men in front of the camera, to the editors, office workers, and adult shop employees."
