From an associate of mine:

Do not accept friend requests from the following:

Odysseus, King of Ithaca -- it is a Trojan Horse attack.

RMS _Titanic_ -- your computer will go down.

Leto II Atreides -- it contains a worm.

Dmitry Ivanovsky -- you will discover a virus.

Moon -- that's not one.

Hormel Meats -- it's probably Spam.

Trey Anastasio -- you will get Phished.

John Jacob Jingleheimer Schmidt -- his name will become your name too.

Boating Accident -- it wasn't.

Rick Astley -- once you're on his friends list, he's never gonna give you up....
