It WILL be a mess. Afaic, they are beyond Blizzard's reach. Worse, they can allow paid service in a "legit" fashion - Czech Republic isn't exactly what I call within reach for Blizzard.
This is utterly stupid. People are making money on Blizzard's assets because Blizzard is too stubborn to make a damned server of their own. This is not going to be pleasant for anybody.
Hopefully Blizzard will be able to flesh out a pristine/legacy server before it goes out of hands.
Also, it's not allowed to post Private servers name. Just a heads up
