Hide Referer for WordPress removes the referer (referrer) from all external links on your blog. It does this by converting all outgoing 
links on your blog using the unrefer.com service and effectively hides your site as origin of the referred link.
For example, Hide Referer for WordPress will convert an external link to wordpress.com, to <a href="http://unrefer.com/?http://wordpress.org" rel="nofollow ugc">http://unrefer.com/?http://wordpress.org</a>.
