I notice Jeff is saying so-long to sitemeter. I’m not sure about it myself. I’ve been using GoStats longer, and I only find sitemeter useful for a few things.
But if any of you want to eliminate this problem, just block cookies from Specificclick. Cookies aren’t really so much a security problem as a privacy problem, in that sites can use it to track your browsing habits.  Personally, I don’t really care if they know what I browse, so I don’t generally block cookies, but for those of you who are concerned, turning off cookies, and only explicitly allowing them for sites where they do useful things, will solve the problem for you.
Turning off referrers can also help protect your privacy, though it can cause some problems with websites that try to prevent hotlinking.
