WordPress: Remove IP-Logging on WordPress Comments (Solution)
Add this to your functions.php:
add_filter('pre_comment_user_ip', 'no_ips'); function no_ips($comment_author_ip){ return ''; }
You’ll still have the comment_author_IP field in the db, but it will be empty…
And to remove existing IP records from the db run this query:
UPDATE `wp_comments` SET `comment_author_IP` = ''
