Why is my blog getting traffic from clicksor?

Tweet

It is a bit weird. As far as I know, clicksor is an ad network. I have no connection to it. But I see that I am getting traffic from it. Here is the example: http://ads.clicksor.com/newServing/yesupSearch/web.php?q=capricorn+aquarius+pisces Isn't that against Google adsense guidelines? Why am I really getting traffic from them? My blog seems to be coming there as an ad. But I never placed it. Can anyone explain me why it is happening?
