Hey peops talking about submission and other bad words:
I don't know what's the law in your countries, but here, in France many peoples got condemened to JAIL for hosting movies or music download website....
Hosting an illegal server of a game like WoW could lead some members of the staff to 1 year of jail or more + maybe hundreds thousands euro fee....
So it's very understandable they give up to avoid being sued not only by Blizzard but by both Blizzard and the french country...
