ZOT is when you delete/ban an account from FR. You want to do this when someone who is a democrat or someone with left-wing opinions post something obviosly left-wing. (eg, a post favoring Clinton over President Bush, an article about how much better Gore might have been, etc.) People who do this are commonly called "trolls".
And what on earth is a Viking Kittie?
Ha ha! The Cult of the Viking Kitties! One of my favorite subjects!
The Viking Kitties are a group of people here on FR that assist the AdminModerator in ZOTing people. We don't do it on our own, you know. The Admin must do the actual ZOT. We will alert him to the premise, then alert each other, and the fun begins!
