I'm sure some people will find a way of using ping for more than just
tracking clicks, especially if multiple ping values were allowed.

And personally, when I'm in little niche area of the web that I'm not

sort of redirect. And if I'm using IE I don't click anything that isn't an
obvious direct url to an typical .com
