Akismet or Automattic Kismet [sic] is a spam filtering service. It attempts to filter link spam from blog comments and spam TrackBack pings. The filter works by combining information about spam captured on all participating blogs, and then using those spam rules to block future spam. Akismet is offered by Automattic, the corporation which employs most of the main developers of the free software weblog platform WordPress. Akismet was launched on October 25, 2005. Akismet is said to have captured over 100 billion spam comments and pings as of December 2013.
Akismet was originally developed to integrate with a plugin for WordPress. It is now included by default in all WordPress builds since version 2.0 and activated in all WordPress.com-hosted blogs. A public Akismet API has resulted in third-party plugins for other platforms. Released under the GPL license, the Akismet plugin is free software, although the code to the Akismet system itself (and the nature of the algorithm used) has not been released.
The Akismet service is free for personal use. To use Akismet with non-WordPress.com sites, it is necessary to obtain an API key. The API key is necessary in order for the site to communicate with the Akismet servers.
