Greedo Shot First? (Plus A Very Strange ICQ Spam)

I'm going to ostracise myself from the majority of the geek community by saying the following:  I don't really care for Star Wars.  I never saw the movies when I was little, my "film buffquot; veneer came during my teens, when I finally had money to spend from my first part-time job.  This means that by the time I finally got around to seeing them, I missed whatever the appeal was to so many other people.  However, I have seen the 1997 special edition and original theatrical version of Star Wars  (I refuse to refer to it as 'A New Hope', I'm sorry.), and I have to agree that the Greedo shoots first scene is one of the worst editting jobs I have ever scene in a major motion picture.  So, for all the Star Wars fans who may read this, here's a link to an amusing comic called "The Emperor's Court", in which Han Solo attempts to prove he's innocent of shooting Greedo first using video footage.

Secondly, the following is the oddest ICQ spam I have ever recieved:

Are you tired from ethereal invisible ghosts of text chats ?
If that's the case, You coming in animated flash-chat
(Address and random gibberish to evade spam plugins removed)

Now, I want to know: what are ethereal invisible ghosts of text chats?  Are they harmful? Should I be worried about them?  How do I get rid of them?  (Do I need to track down a bell, book, and candle and perform an exorcism? If so, since they're ghosts of text chats, will reading from the book you use for the exorcism in Zork I^* work?)  Should I draw up a circle of protection prior to logging on to ICQ? I need to know these things; I don't want to be putting myself at risk here.

Oh ye who go about saying unto each: "Hello sailor":
Dost thou know the magnitude of thy sin before the gods?
Yea, verily, thou shalt be ground between two stones.
Shall the angry gods cast thy body into the whirlpool?
Surely, thy eye shall be put out with a sharp stick!
Even unto the ends of the earth shalt thou wander and
Unto the land of the dead shalt thou be sent at last.
Surely thou shalt repent of thy cunning.
