Akismet

Akismet is a key tool for any WordPress user looking for effective spam protection. This plugin checks comments and submitted forms on your website against a global spam database to prevent malicious content from being published. Users can clearly check the spam comments that Akismet captures in the admin interface of their blog. Akismet is also ideal for WooCommerce users, as it effectively protects e-commerce sites from spam comments and spam, increasing the security and user-friendliness of online stores.

Akismet's main features include automatically checking all comments and filtering out those that appear to be spam. Each comment has a status history, so you can easily see which comments have been caught or approved by Akismet and which have been flagged as spam or unspamed by a moderator. URLs are displayed in the comment body to reveal hidden or misleading links. Moderators can see the number of approved comments for each user.

Akismet also offers a discard feature that completely blocks the worst spam, saving disk space and speeding up your website. To use Akismet, you must obtain an API key from Akismet.com. Keys are free for personal blogs; paid subscriptions are available for businesses and commercial sites.

Akismet is open source software that was developed by the Automattic team. This plugin is free, but also offers additional paid commercial enhancements or support.
