I also understand that he put some text from PH on his site. Whether that was within Fair Use under italian law I don't know. In my book it seems to be a rather minor infringement made by a dedicated fan who put a lot of effort into that site.Also, let's be fair here. From what I understand, Ema pretty clearly had copyright infringement on the site. You might disagree about the remedies, but you probably have to give into that (if there indeed was complete verbatim text of non-open feats, spells, etdc. on the site).
So, do you consider such a fan your enemy or your ally? Leniency or all out war?
