Mao Zedong

Wikipedia's article on Mao Zedong is currently semi-protected, but it has been vandalized a couple times.

Chemis
On 5 November 2008 at 7:17 PM UTC, the entire page read:

clearly, mao zedong created malic acid, he was the lead chemis behind warheads. and he killed chinese people and something about a red book

Mao did not have many friends. So he decided to torture people with the warheads.

Mao did not know it, but he had a secret lover named kristin.

She eventually went to declare her love to him, but it was too late. He ate too many warheads and died.

Mao Zedong, the Evil Bastard
On 21 December 2008 at 8:57 UTC, the entire page was replaced with:

Mao Zedong was an evil bastard. who was also the biggest murderer of the 20th century and killed more people than Joseph Stalin and Adolf Hitler put together and yet remains to be a revered man by the Chinese people. Fuck all communist governments. Fuck all socialist governments. the "Peoples Republic of china" is not by the people and certainly not for the people there should be a great revolt in china so the bastard oppressors can be killed. china is long overdue for freedom. although the Chinese people can not view this because the assholes in their government block any website that mentions the words freedom and, or democracy you should rise up and at least make some noise about this injustice and word will somehow get to china and a revolt will come. god bless

The liberal Bolshevists who run Wikipedia obviously thought this was too biased, as this revision was almost simultaneously reverted.
