Unfortunately, yes there are people who run private servers for world of warcraft.

Private servers are known to be buggy as heck. It is better to just play on the live official servers.
This is the problem with private World of Warcraft servers. They are full of bugs. You should go play on the live official servers. Much better.
This is what I'm currently downloading. http://www.antwow.com/ Games in this include, World of Warcraft1.2GB) World of Warcraft: Burning Crusade(4.6GB) World of Warcraft: Wrath of the Linch King (15GB)
