I'm doing a competition for my school where you have to create an ad about internet piracy. I want to have internet pirates getting pwned by ninjas, as the theme of the ad. Do I have to get permission from anyone to do so? I've already sent a letter to realultimatepower asking.

Is this idea even good?

Pirates are destroying UK creative industries
Ninjas flip out and kill people.
Why did you create another thread when the other one got closed? -.-

May the Force be with You.
