Summary: Formed in 2007 and operated out of Limassol, Cyprus, xHamster has worked its way up to become the 20th most-visited site on the internet. The site boasts 10 million members and hundreds of millions of daily visitors despite being blocked by a number of governments around the world.

Being in the pornography business poses unique moderation challenges. Not only do moderators deal with a flood of both amateur and professional submissions, they must take care to prevent the uploading of illegal content. This goes further than policing uploads for unauthorized distribution of copyrighted material. Moderators must also make decisions -- with facts not in their possession -- about the ages of performers in amateur videos to prevent being prosecuted for the distribution of child pornography.
