We'll create fresh WordPress site with WP Spam IP installed. You have 20 minutes to test the plugin after that site we'll be deleted.
WP Spam IP works right away when you activate the plugin. No more settings needed. The IP’s in the plugin will be added automatically to your Comment Blacklist.
When a comment comes from an IP adress located in the Comment Blacklist the comment will be marked as spam right away. The plugin does not delete anything and it is up to you if you want to delete the comment or not.
