It is not known with certainty what the causes of insanity are, but it's probably a safe bet that it has something to do with white trash whores smoking meth while they had rotting little shit-bags festering in their guts.
On the Internets about 100% of the people are insane. This is most likely due to online communities, fetish porn, and the fact that insane people can't hold jobs so they have nothing better to do than waste their time OL.
