I’m a signature virus! Copy me into your signature, please!

However, many people were genuinely scared, so I had to remove it from my sig. Later, I was using an X-Face (http://de.wikipedia.org/wiki/X-Face), which was supported by Sylpheed, the mailclient I was using some years ago. These days, I use a 20 lines long disclaimer like this one:
