There are 12.5 million people playing World of Warcraft. I suspect many, many of them have a craving for Coke and Cheetos while playing. I'm not going to make the leap that because a bunch of gamers want Coke and Cheetos that WoW causes people to want junk food.The expression "World of Warcrack" is widely used for a reason. Many, many people experience the same thing.
As has been said, people have been trying to prove for YEARS that the Internet and MMOs exert some sort of sinister pull over users. The reason you haven't seen the proof about it on the cover of Time Magazine is that they haven't been able to find it.
