Never saw this before - { www.statcounter.com/ (Exit Link) }

[quietsounds]

I have never seen this before in my visitor paths. Any ideas?

" Dec 2 05:11:55 PM www.statcounter.com/ (Exit Link) "

My counter is invisible, always has been, and I just checked the page to make sure. So I'm not sure how anyone could have exited the site to statcounter.com without a visible link.

I don't use adsense or anything else like it if that matters.

Thanks for any help.
