Delink Comment Author
This plugin gives you the ability to remove the link a commenter left as their URL without removing the entire comment, as valuable and insightful comments are not always attached to appropriate links.
Previously, comment URLs could be manually removed through the comments page. With Delink Comment Author, your new comment e-mail notifications will now include a link that allows you to remove these URLS with a mere click. This function is also included in the comments list in your admin area.
