Whether or not you agree with how he went about it or the sanity behind his desire, there's no disputing that Gullerbone was indeed the first player to get a character to 70. This video shows the method behind his madness, just in case you want to go and farm your way to 70 too.
Because I'm never one to shy away from a good discussion, I'll just add my opinion here: As long as Gullerbone enjoyed himself, either in the activity of getting to 70, or in the result itself, then there's no harm here. He's not hurting your game, he's just working the game mechanics to reach an end that he desired. That's the great thing about an MMO such as WoW - there are so many options that you can explore for your $15 a month.
Oh, and one more quick comment: Is it just me, or can you really tell the difference between European-made videos and North American-made videos by their choices in music?? Not 100% of the time, but enough to make an educated guess as to the continent of origin.
