== Description ==

Major features in Akismet include:

* Automatically checks all comments and filters out the ones that look like spam.

* Each comment has a status history, so you can easily see which comments were caught or cleared by Akismet and which were spammed or unspammed by a moderator.

* URLs are shown in the comment body to reveal hidden or misleading links.

* Moderators can see the number of approved comments for each user.

* A discard feature that outright blocks the worst spam, saving you disk space and speeding up your site.
