I have never understood the absurd idea of hiding referrers.
Case in point, here's what I often see when checking my site's statistics:
Tell me, gentle reader, am I overreacting when I say I don't need this kind of visitor?
Am I being weird when I say I feel like outright banning these people or redirecting them to a special page?
"Since you are so concerned about your privacy that I'm not allowed to know how you came to my site I'm not even going to let you see my content. It might offend you. Or your searchterm might offend me. Either way you're not welcome here. Move along please. Nothing to see."
If it's none of my business to know how someone came to my site why are they here? What are they doing outside of http://localhost/?
