Basically, private servers are free servers for P2P MMOs like WoW. Sometimes they're private servers for F2P MMOs like Maplestory to get high level caps, free premium content, custom content, and etc.
For me it depends on the game, though any private servers would be considered an act of piracy. For example if its a F2P MMO and they want to fix or change something for themselves that I can sort of understand but it would still be a form of piracy
