Dude they're just making up bullshit, they're saying that the programs that were on your site had titles, computer code, objects, characters, character names,
stories, dialog, catch phrases, locations, artwork, animations, sounds,
musical compositions, audio-visual effects, methods of operation, any related documentation, and "applets" that were copyrighted by blizz.

You should just make a readme in all the dloads and put "Alltitles, computer code, objects, characters, character names,
stories, dialog, catch phrases, locations, artwork, animations, sounds,
musical compositions, audio-visual effects, methods of operation, any
related documentation, and "applets" are copyright Blizzard entertainment

Those assholes are looking for anything that could shut down a Blizz hacking site.
