This is a WordPress plugin that will stop WordPress from performing self pingbacks.
When a blog links to other blogs it will perform a pingback to let the blog owners know the content is linked to. By default WordPress will do the samething even with internal links, so you will be notified there is a link.
This WordPress plugin will stop this default behavior and I really like this plugin and my recommendation for you to install this on your site for better performance and don’t worry this precious plugin s just for no cost.
