Nasty comments from a nasty person

To the person who left me a nasty comment (which was misspelled, by the way):

You obviously don't know that I have Site Tracker software in my blog, and I know who you are, where you are, how long you were at my blog, and what pages you looked at...I even know what kind of computer you were on.
Don't muck up my blog with your lousy attitude...go somewhere else and be ignorant.
