You shouldn't be able to see your own website within your referers.
I've taken a look at your website and its not the same URL as you have registered.
If you use our DNS servers, we create several subdomains as well as the usual WWW used in WWW.yoursite.com
in your case, someone has gone to
http://yoursite.com without the WWW and this isn't your registered site, so our system redirects your customer to
http://www.yoursite.com and logs the
http://yoursite.com as a referer.
Hope this helps.
