How to Delete All Spam Comments on WordPress Multisite Network

Tripawds is a user-supported community. Thank you for your support!

This one is for WordPress mulitisite admins out there looking for a way to bulk delete all spam comments across their entire network and reduce database overhead. Tripawds members can feel free to skip the geekspeak.

Why WordPress stores spam comments in the first place is beyond me, but that’s a different discussion. When I discovered our wp_site_comments table was consuming more than a gigabyte of the database for our Tripawds Blogs multisite network, I was happy to find this gem of an SQL query to delete spam comments and modified it slightly to do so from all blogs at once.

DELETE FROM wp_site_comments WHERE comment_approved = 'spam';

In a matter of seconds I reduced the size of our database by more than a gigabyte!

How To Delete WordPress Network Spam Comments

Yes, WordPress does provide the ability to delete spam comments from the dashboard, but not from all sites on a multisite network at once. This simple query allowed me to delete spam from all sites in one batch. By using phpMyAdmin to execute this SQL query the job is completed quickly, efficiently and without the need to visit each site’s dashboard or the memory overhead created when WordPress attempts to process a large number of comments.

It’s that easy!

  1. Backup your database (Highly Recommended)
  2. Launch PHP MyAmin
  3. Load your network’s database
  4. Click the SQL tab
  5. Run the query above
  6. Optimize the wp_site_comments table to remove any overhead

What does this mean to Tripawds Members?
