What most people do not understand is that it is illegal to use someone else's intellectual property without permission, even if you do not make a profit from it.

This is what I would call a typical unenforceable law - fans can reproduce and distribute corporate IP an order of magnitude faster than the corporate lawyers can track them and shut them down. Paramount, for one, seems to understand this. If other corporations don't, well, they have the law on their side. Shut down your site and move on, they probably won't keep after you if you stop distributing their IP.

If, on the other hand, you were making a profit off their IP, then you are a full-fledged IP pirate and things could get ugly. So don't.
