What is the most piracy friendly porn companies?

Piracy not privacy

Companies that don't issue a DMCA request on their videos when they are shared outside their websites.

They aren't, but chasing down websites in other languages is a pain in the ass. The Japanese see basically all non-Japanese people as copyright infringers. I've downloaded JAV that's bookended and watermarked with Chinese ads because the Chinese have the gall to do that, not the Japanese who probably see it as an annoyance and primarily target the domestic Japanese market anyways.
