The founders of Snopes.com research and publish their findings on the veracity of urban legends and other stories and rumours, so the original content the website publishes is based in fact. However, the urban legends and other stories the site features are either fact or fiction.
Snopes.com has a rating scale for the truthfulness of urban legends and other folklore stories. The "true" rating is applied to stories that are completely factual or urban legends are based on real events. The "mixture" rating is for stories that have elements of both fact and fiction. "False" denotes stories that are completely implausible. The "outdated" rating is assigned to verified stories in which the circumstances have changed. Finally, the "legend" rating is given to urban legends that are plausible and have likely happened at some point in time.
