Copywright laws are extremely fickle. Thousands of lawyers with nothing better to do are arguing about copywright infringment. Unfortunately with computers, everything deals with making a copy of the original.

For example, this text you are reading is a copy.
This smiley is a copy of its original. your computer has downloaded an image off the web and then presented it you on the computer screen.

As most of you know, fansubbing, in the eyes of the law, is illegal. Any editing, and mass distribution of copywrighted material can be considered an infringment. Whether a group decided to enforce those copywrights is thier call. (Cough, Bandai, cough)

But what makes these eBay cases worse is that they are taking a copywrighted, altered, mass-distributed (without the copywrighter's consent) and SELLING it.

Of couse I'm not trying to lecture anyone. Just stating the some unlikable facts.
