The year 2012 is most certainly sponsored by letter "F". Like fandoms, freaks and few other words starting with "f" I'm not supposed to write in the first sentence.
After reading this article (well written for a change), I realized that blaming only fandoms or only managers is just stupid. We should also blame artists themselves for being idiots. Oh we know their managers are lazy and greedy, they care little about those idols yet care a lot about the revenue those are generating. It never occurred to them that with fandoms becoming more and more violent, idols need some devil's invention like bodyguards maybe? So that no one would go through to slap an idol or grab him by the head. It's an insane situation, yet it stands still because no one cares to do anything.
