Curiosity about my referrers

Would anybody care to explain the "Not Your Business!" that's appearing on my referer page? Is that an anonymizing proxy, Opera, or something?

I don't mind of course, but I would like to observe for the benefit of who ever is doing that that right now, my referers page is all the feedback I get about this site; I do not have access to the web logs or anything else like that, so if it doesn't show on the referer page, I don't know about it. (In theory, a thousand people could be loading my site from their bookmarks every day, with no referrer, and I'd never know.)

Clarification on my Right to Reply comments

There have been many good posts on Europe's Right of Reply policy, such as Declan McCullagh's column, this from Jeff Jarvis, and a whole Slashdot discussion.

I wanted to clarify my own opinion: I'm willing to call the right of reply a cultural difference to the extent that the right of reply consists solely of adding a link to the reply. This should go for everybody nowadays, including even established media; it should be sufficient for a television program to say "Go to our website for a link to blah's reply." with a link in a suitably prominent location.

Right of reply, theory and practice in the EU

Euro-blogging & the Right to Reply [LawMeme]: The proposal establishes a "right to reply" for anyone criticized online. Web sites - both news sites and individually controlled sites, moderated mailing lists and even blogs could be required to give subjects of criticism the opportunity and ability to reply.

This is the first post I think I wouldn't have bothered with if I didn't have my communication ethics essay to back me up.
