Please do as timethief suggests and contact staff, repeatedly, about this problem. It's a huge issue here at wordpress. Your blog stats are essentially useless because the numbers are inflated by referrers who haven't referred a single view. Your link does not appear on their sites. I don't know how they do it but it's a major scam.
DO NOT click on the links. Do not post them anywhere. That's just fueling the fire.
I have emailed wordpress support repeatedly with this issue and most of the time they are silent, accept for "we're working on it." The last time I contacted them, however, someone was kind enough to explain how they're trying to solve the problem.
That doesn't mean YOU shouldn't contact them. Please, complain. And send them lists of the fake URLs so they can keep track of where it all comes from.
If you don't know HTML, here's how to get the full URL. Click to your referral page, go under "view" in your browser window and choose "view source." The URLs start about halfway down the page.
Look for this tag: <div id="referrers" class="sumdiv">. That's the beginning of the URLs. Below it a few lines you'll find this tag: <h4>Today</h4>. That's where the day's referrers start.
Each link starts with this <a href=
And will end with this
Everything in between is the URL. You'll be able to recognize the beginning from the first few words you normally see in your browser.
Digging through the page the first time may seem laborious, but you'll pick it up quickly. Please report the spammers and encourage wordpress to fix the problem.
WordPress is a terrific free service, and I'd like to stay here ... if we could only get real stats.
