Within the U.S, most websites containing pornography have taken voluntary steps to ensure that visitors to their sites are not underage. They warn minors and those not interested in viewing porn not to view the site, and require the viewer to affirm that he or she is at least 18 years old, but this has little effect in preventing access by minors to porn. Within nations that allow some types of pornography, models are usually required to be at 18 years old and there are record-keeping laws for the restriction.
