Akismet is a spam filtering service that filters spam from comments, trackbacks, and contact form messages. The filter works by combining information about spam captured on all participating sites, and then using those spam rules to block future spam. Akismet is offered by Automattic, the company behind WordPress.com.〔(【引用サイトリンク】title=Automattic.com )〕 Launched on October 25, 2005,〔(【引用サイトリンク】title=Live Live )〕 Akismet is said to have captured over 100 billion spam comments and pings as of October 2013. == History == The founder of Automattic, Matt Mullenweg was inspired to create Akismet so that his mother could blog in safety.〔(【引用サイトリンク】url=http://mixergy.com/interviews/the-biography-of-wordpress-with-matt-mullenweg/ )〕 In 2005, there were ongoing discussions about how to deal with comment spam. At the time, there were a few plugins around, such as Spam Karma and Bad Behavior, and Matt was also working on his own anti-spam solution. His first attempt was a JavaScript plugin which modified the comment form and hid fields, but within hours of launching it, spammers downloaded it, figured out how it worked, and bypassed it. This is a common pitfall for anti-spam plugins: once they get traction, spammers pay attention and they quickly figure out how to bypass it. In late 2005 Matt launched the Akismet plugin for WordPress. Akismet (which stands for Automattic kismet) is a way of dealing with spam in aggregate, a crowd-sourced spam-fighting tool.〔(【引用サイトリンク】url=https://github.com/WordPress/book/blob/master/Content/Part%203/17-akismet.md )〕 Each time someone posts a comment to your website, Akismet checks it against all the comments in the database. If it's spam, it's deleted, if not it lands on your site. If spam gets through and a user marks it as spam, the comment is added to the database. So the pool of spam comments is constantly widening, making Akismet into something that is more effective over time. “It’s like all the kids on the playground ganging up against a bully.” says Matt,〔(【引用サイトリンク】url=http://archive.wordpress.org/interviews/2014_04_17_Mullenweg.html#L97 )〕 “Collectively we all have the data and the information to stop spammers, certainly before they’re able to have a big impact.”〔 The name, Automattic kismet (Akismet for short) was suggested by Matt's sister Charleen. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Akismet」の詳細全文を読む スポンサード リンク
