I think you will know this situation: You go to your WordPress admin panel and there are 100′s of pending comments including spam links. Now you can manually remove every link from a comment that you would like to approve. This will take you much time. I will now give you step by step instructions for a really fast and simple solution to remove all spam links of unapproved comments at once:
1. Open your WordPress mysql database in phpMyAdmin.
2. Find out the name of your WordPress comments table (mostly it is “wp_comments”).
3. Click on the “SQL” tab at the top of the page.
4. Insert the following mysql command to the text box and click “Go”.
If your WordPress comments table has another name than “wp_comments”, replace it with your table name.
Within seconds all links of your pending comments are removed. You will save a lot of time with this solution. Now you can check the comments and approve some if they are good, without having 100′s of spam links in your blog post comments.
