Some places are nicer then others when it comes to fan websites I have heard. I heard marvel hates them, or use to, no idea if they still do nor not. Dc and bbc don't care really. The bbc even turned a blind eye after dr who was canceled and in the interum folks were making their own fan made dr who movies and you could get them for free, like they are turning a blind eye to loose cannon doing their reconstructions of lost episodes. It all depends on the corporation from what I heard and their attitude.
