An owner of a lame website or blog, who spams internet message boards with bogus conversations among his many IDs. The goal is to give the impression that the initial message contains something of considerable interest to a number of people. That initial message invariably contains a link to said lame website or blog, to which the click whore is attempting to draw attention and internet traffic.
"These same nine IDs keep showing up in the same conversation on twenty different message boards. That "hot_stocks" blogger really is a click whore."
