I don't know why this made me laugh as hard as it did. For starters, some of the advice is good... I'd encourage you to read a book or take a martial arts class whether or not you're going to play WoW any longer. Books are fun. I sometimes read a book while I play WoW, but I suppose that wouldn't really be what the article is going for.
Part of the problem would be that I don't want to dismiss the article out of hand. After all, "Psychological dependence does not have to be limited only to substances; even activities and behavioral patterns can be considered addictions, if they are harmful, e.g. gambling, Internet use, usage of computers, sex / pornography, eating, self-harm, vandalism or work" according to Wikipedia's article on the subject. I suppose for me it's the 'if they're harmful' qualified that gets me. So far, WoW has given me and some friends some fun times and a chance to do something as a group when we can't all get together in one place, it's allows me to make new friends who live well outside my range, and it's allowed me to work out some frustrations that would otherwise go without venting. So for me at least WoW is a game that I play and a source of fun. Clearly, for some people WoW has become a big part of their social lives. And anything you care about can become an obsession or an addiction.
But still, I cannot help but laugh when I see advice like "burn yourself out by finding ways to cheat...Find a private server to play on" or my personal favorite, "Sabotage your WoW future". I'm kind of surprised the original author didn't feel the need to add "Seal yourself in a lightless vault with only tins of tomato soup for sustenance" or "hire an angry man to break your thumbs if you go near a keyboard'". It just seems so hyperbolic and reactionary that I can't help but be amused by it. The funniest part is when he advises people to play on private servers, warms them that this may get their account banned as it is a violation of Blizzard's ToS, and then later advises people to violate Blizzard's ToS to get their accounts banned. I don't think most players have to go to these extremes, I know I don't play so much that I feel this kind of fear over it.
