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.
