Hello,
Today killing some time I collected some “free url redirection services”, so in the case that you want to hide your referer to post links on your blog, some forum, or whereever you want, you could try it:
http://canalonline.vodafone.es/cpar/do/sso/go?type=1&destination=https://www.google.com
http://www.fileheaven.com/download.aspx?id=20805&p=&url=http%3a%2f%2fgoogle.com
http://www.datumconnect.co.nz/ra.asp?m=1&p=&url=http://www.google.com
http://www.segundamano.es/redir?s=modificar&url=http://google.com
The best of all is that these services are 100% AD free
