Reddit today said that it will ban sexually explicit photographs that have been posted without the permission of the person in the pic.

"No matter who you are, if a photograph, video, or digital image of you in a state of nudity, sexual excitement, or engaged in any act of sexual conduct, is posted or linked to on Reddit without your permission, it is prohibited on Reddit," the company said today.

Reddit will also remove "violent personalized images" when notified of their existence.

The changes are part of a revised privacy policy that will go into effect on March 10, Reddit said. Going forward, if you find an inappropriate photo of yourself on Reddit, notify Reddit via contact@reddit.com, "and we will expedite its removal as quickly as possible," the updated policy says.

Reddit will "share how often these takedowns occur in our yearly privacy report."

The move comes in response to the September hack of celebrities' phones, which resulted in naked photos of several A-listers showing up on Reddit, Twitter, Imgur, and other corners of the Web. Some of the photos were fake, but others - like those from Oscar-winning actress Jennifer Lawrence - were genuine.

Sites like Reddit were criticized for not doing enough to remove the offending images in a timely manner. Today, Reddit said it "missed a chance to be a leader in social media when it comes to protecting your privacy -- something we've cared deeply about since Reddit's inception. At our recent all hands company meeting, this was something that we all, as a company, decided we needed to address."

But the celeb hack is not the only incident of its kind of Reddit. Remember Violentacrez, the self-proclaimed "creepy uncle of Reddit"?

Reddit is also planning tutorials for moderators that "will help anyone from experienced moderators to total neophytes learn how to most effectively use our tools." The first of those tutorials, which covers "the basics," is now live on YouTube (embedded below).
