I'm not sure about just hosting it "for no reason". It's a very spammy event for the forums, more spammy than eShroom Corp and SNN himself (waaaaaaaay more)
. And as pointed out by RanAS, it's also very costly for the server.
I think we can think out better and less spammy events of that sort for the future, though. Something in the style of forum games, not necessarily related to C3. I'm sure Impetus had some things in mind actually.
