Sounds like "走火入魔", a mental state mentioned in many Wuxia/Chinese-Kongfu-Fantasy novels when a rigorous 内功修炼(internal training/meditation)goes bad, which I thought was a myth.

And about the reason why these sites are blocked: just BECAUSE THEY CAN! (They even blocked github for mysterious purpose once!) There is no public rule/law/principle to tell us why a foreign site is blocked. The just kill sites silently and pretend nobody cares.
Fortunately enough, HackNews has not been blocked, yet.
