The most popular online destination for deepfake porn shut down permanently this weekend, 404 Media reported.

“Mr. Deepfakes” drew a swarm of toxic users who, researchers noted, were willing to pay as much as $1,500 for creators to use advanced face-swapping techniques to make celebrities or other targets appear in non-consensual pornographic videos. At its peak, researchers found that 43,000 videos were viewed more than 1.5 billion times on the platform. The videos were generated by nearly 4,000 creators, who profited from the unethical—and now illegal—sales.

But as of this weekend, none of those videos are available to view, and the forums where requests were made for new videos went dark, 404 Media reported. According to a notice posted on the platform, the plug was pulled when “a critical service provider” terminated the service “permanently.”

“Data loss has made it impossible to continue operation,” Mr. Deepfakes confirmed, while warning not to trust any impostor platforms that pop up in its absence. “We will not be relaunching. Any website claiming this is fake. This domain will eventually expire and we are not responsible for future use. This message will be removed around one week.”

It remains unclear exactly which service cut off Mr. Deepfakes, but researchers noted that among the “most crucial components” that deepfake creators needed to keep generating the content was “free-tier cloud GPU access” provided through Google Colab notebooks.

Google did not immediately respond to Ars’ request to comment on whether that access was recently yanked.

Downfall follows Take It Down Act passing

The downfall of Mr. Deepfakes comes just after Congress passed the Take It Down Act, which makes it illegal to create and distribute non-consensual intimate imagery (NCII), including synthetic NCII generated by artificial intelligence. Any platform notified of NCII has 48 hours to remove it or else face enforcement actions from the Federal Trade Commission. Enforcement won’t kick in until next spring, but the service provider may have banned Mr. Deepfakes in response to the passing of the law. Last year, Mr. Deepfakes preemptively started blocking visitors from the United Kingdom after the UK announced intentions to pass a similar law, Wired reported.
