G'day mate, was indeed the staff member who banned you. Here on this server we take these kind of threats extremely seriously and it's never something you want to joke about. All of our Staff are under instructions to iP ban anyone who makes a threat against the server, even if it's a joke.
The fact that you tried your little stunt seconds after I banned the first guy sold it to me even more and promptly got yourself iP banned as well. No amount of "XD" or "sorry I was joking" will stop us from banning you.
I'm going to give you the benefit of the doubt in this case but due to the serious nature of the offence I'm keeping you banned for a full week from my post. If you make a joke like this in the future, I will ban you again with no chance for appeal.
See you in 7 days.
