Nyaa Torrents

Nyaa Torrents (named for the Japanese onomatopoeia for a cat's meow) is a BitTorrent website focused on East Asian (Japanese, Chinese, and Korean) media. It is one of the largest public anime-dedicated torrent indexes.
History.
In 2011, some users of the site were targeted for copyright infringements. The site was a target of a large DDoS attack in early September 2014.
On 1 May 2017, their .se, .eu and .org domain names were deactivated, with the site's moderators later confirming that the owner took it down voluntarily. In the following weeks several forks, partially based on Nyaa code and database of torrents, were started, each using 'nyaa' in its name.
In the official FAQ posted by the community that surrounded Nyaa it is said that some data between 2016 to May 2017 was lost and there wasn't a reputable backup of the Nyaa database for that time period.
In June 2017 TorrentFreak reported that Germany based Goodlabs put up a fake version of the .eu site in an attempt to get users to download malware.
As of March 2021, the .si fork and the .net (formerly .pantsu.cat) fork are the only two forks remaining.
