Actually I came here wanting information on the client server model and information about some more of the technical details having information about private servers is needed simply because of the lack of info about fundamental technical aspects of the game via the reverse engineering and  community that seems to be built around them we get useful information about architecture of how wow is put together this is interesting for some poeple of course nonwithstanding I am sure blizzard wants as few people as possible to know about private servers They exist and there existence provides useful insights into the game and communities around them
