This plugin is intended to make the comment-moderation for the blog-owner a little bit easier. It does not detect comment-spam on its own. To successfully prevent spam, it should be used as an addition to the spam-protection provided by Akismet and Spam Karma.
This plugin adds a small button to every comment. This button will only be visibly to a logged-in blog-admin (that is a registered user with a user-level of 10).
When you press this button, the URI of the commenter will be replaced by the URI you can specify at the plugin?s option-page.

Comment URL Control

This plugin will allow you to remove an unwanted author-URI entered by a commenter with one single click of your mouse.

Some people really like that WordPress sends pings from your own site to your own site when you write posts; it gives them a trail of related posts.
Some people do not like this behavior; it clutters up their comments.
This plugin disables intra-blog pinging.
Once activated, there’s nothing for you to do. However, head to Settings -> Discussion and you’ll find a field in which you can, if you wish, specify more domains that won’t be pinged. Why? Well, maybe you often refer to other sites that you maintain or, particularly, you run a multi-site and don’t want each blog pinging the other – specify a list here and you’re sorted.
