Encourage and then let him fall? Either way...
The cost of a dedicated server depends, a 100mbit dedicated = 1000$ a month.
And believe me, self hosted server with the usually 3mbit nett is NOT good enough for more than 30ppl if you code it really well.
Software for pirated Wow Server? well, the server isn't everything, they didn't need to make 3D models, textures, map the worlds, code the game play. They just took what Blizzard made and tried to make a copy of their servers.
Blizzard is a big company, they have existed for VERY long, and had a good grip on the marked, they had the recourses and the time to make a MMO game.
If someone with a game making team, and experience to make an MMO came here asking for help, no one would disagree, then again, they wouldn't need to ask for stuff like tutorials, servers etc... you need to KNOW how to make an MMO game, not just suddenly want to start one.
If this had been in the Recruitment forums, with a good plan, and asking for people to join, it would have been a different story.
