Akismet is the most powerful anti-spam service for the web. Akismet works by checking all your comments against our constantly-growing global spam database to remove irrelevant, malicious content before it gets published and damages your site’s credibility.

Akismet gets increasingly effective over time: the more it learns, the more it protects. Its algorithms are continuously learning from content marked as spam across websites, so it more accurately detects and removes spam from sites in the future.

When Akismet is enabled on your site, only the personal data needed to carry out Akismet’s core function of protecting your site against comment spam is collected from commenters on your site. We do not sell the data you send to the Akismet service, and we do not keep it for long. We have short retention periods of between two weeks and ninety days for the vast majority of our spam-related data, at which point it is automatically deleted from our databases. Anyone can opt-out of all long-term tracking for the very small subset of data we do keep longer by using our contact form. For more information, please visit our Privacy Notice.
