Memo to foolhardy companies: Anonymous does not like having its Intellectual Property rights violated. The Register reports that the famed hacker collective is in a state of outrage because a French company called E-Flicker has filed a copyright application for Anonymous’s official headless-man logo and slogan.

“Their arrogance and ignorance of what they have done will not go unpunished,” the group threatened in a new YouTube video. “Anonymous will take down any business they have going on the internet and the ninety-nine per cent will not stop until the registration has been revoked and a public apology has been made. The name of Anonymous will not be the whore of the world.”

Left unsaid is the fact that Anonymous could have saved itself all this trouble if it had just bothered to trademark its own logo for itself. And of course, E-Flicker probably should pick its opponents more wisely since Anonymous will likely grind its online business to a screeching halt with minimal effort.
