Webmasters can use this tool to prevent their site from appearing in the server logs of referred pages as referrer. The operators of the referred pages cannot see where their visitors come from any more.
Using the referrer removal service is quite easy: http://www.yourdomain.com/redirect.php?go=http://www.whatsmyreferer.com/ produces an anonymous link to whatsmyreferer.com which prevents the original site from appearing as a referrer in the logfiles of the referred page.
No database needed. Just upload the script, make a few changes on the landing page if you want to and thats it.
