So ...

This awesome plugin blocks spam comments and trackbacks effectively, without captchas and without sending personal information to third-party services.

More than that, it is free of charge, ad-free and 100% GDPR compliant. Here's a quick feature/settings overview:

• trust approved commenters
• trust commenters with a Gravatar
• consider the comment time.
• allow comments only in a certain language
• block or allow commenters from certain countries
• validate the IP address of commenters
• search local spam database for commenters previously marked as spammers
• notify admins by e-mail about incoming spam
• delete existing spam after n days
• select spam indicators to send comments to deletion directly
• optionally spam-check comment forms on archive pages
• display spam statistics on the dashboard, including daily updates of spam detection rate and a total of blocked spam comments
• etc
