Creators of porn websites have been set free of onerous confirmation of age record keeping laws, after the Unites States Court of Appeals found that the law requiring the keeping of these records was unconstitutional. Previously, porn websites hosted in the United States had to keep records confirming that all performers shown on their sites were of a legal age. More recently there has been some suggestion that these requirements would be extended to all sites showing porn, potentially destroying sites such as YouPorn.com and Pornotube.com (both NSFW) who rely on user generated content and therefore would not have access to records.
