Pit of Voles

The Pit, also known as the Pit of Voles, the Sewer, the Reeking Pit of Open Sue-age, and fanfiction.net, is the biggest source of badfic. This is because, while there are rules about spelling, grammar, and content, the site is so huge that they are rarely enforced. It also hosts fanfiction for a wide variety of fandoms, making it very easy for users to write stories set in worlds they know almost nothing about.
