The issue is nonconsensual intimate visual depictions. Sites have to take down such content on request. If they don't have a policy that satisfies the requirements, the FTC might issue fines. If they don't follow valid requests, there might be fines/criminal charges. I guess the situation might be more problematic for users who are uploading such content, as they might be criminally liable. (The respective law was enacted a little more than a year ago.)
