Comment Author URL Stripper
When writing comments, a lot of people type in google.com, yahoo.com, hotmail.com, and various other web sites which don’t belong to them. This plugin strips out the comment author URL whenever it contains anything from a set of words that you specify in the Options screen. The URL will never make it to the database.
For more information or to download the plugin, visit the Comment Author URL Stripper plugin page at WordPress.
