You can easily bulk delete pending comments in WordPress by installing a useful plugin called WP Sweep.
WP Sweep allows you to clean up your comments with just 1 simple click. Here’s how you do it:
- Install WP Sweep by going to Plugins -> Add New -> Search for “WP Sweep”.
- Activate the plugin.
- Go to Tools -> Sweep in your WP dashboard.
- Scroll down to Comment Sweep -> Pending Comments and Hit “Sweep”
That’s it. You can also bulk moderate unapproved and spam comments as well. This is one of my favorite WordPress plugins and it will save you a lot of time and frustration!
