Facing pressure from its payment partners, Patreon is, once again, cracking down on adult content.

As Motherboard reported Thursday, a number of adult content creators have been suspended from the crowdfunding site for "implied nudity" as of late. Now, we know why.

"We have been ramping up the proactive review of content on Patreon due to requirements from our payment partners," a Patreon spokesperson told PCMag in an email. "Our community guidelines have not changed, and when we discover a page that is not in compliance with our guidelines we place that page in a state of suspension and work directly with the creator to bring them back within our guidelines."

Patreon added that it has "doubled the size" of its support team so it can "get back to creators and give them 1-1 guidance as fast as humanly possible."

Patreon's payment partners include PayPal and Stripe, but Motherboard says "the pressure to turn sex workers away comes from major banking networks."

The crackdown comes after Patreon in October updated its community guidelines to make its rules around porn a lot stricter.

"You can't use Patreon to raise funds in order to produce pornographic material such as maintaining a website, funding the production of movies, or providing a private webcam session," the updated policy reads. Users are also prohibited from selling "pornographic material or arranging sexual services" as a reward for their patrons.

Motherboard spoke to one adult content creator affected by the crackdown who said Patreon didn't even offer a warning before suspending their account for "public nudity."

"I didn't get any warnings, just an email and notification that my account was suspended," the photogropher, Kate Victoria, told the news outlet. Victoria also claims she didn't even have any fully nude images publicly available.

"There wasn't a single nude body part showing that I would consider to be adult-orientated," she said.
