One of the great unwritten rules of Wikipedia is that you don't criticize Wikipedia on Wikipedia. Sure, there is an article called "criticism of Wikipedia," but outside of that article, you're not allowed to criticize Wikipedia in any way. Doing so on your user page is one of the surest ways to get your user page deleted.
Recently, Eddie on Yahoo! Answers asked "Why do some Wikipedia admins insist that the rules of Wikipedia be applied all throughout the Internet?" GrimJack, a notorious Wikipedia apologist on Answers, answered the question with another question: "Do you have any specific examples of this?"
Well, I have a specific example for you: Nihiltres and Coffee seem to think that since Gregory Kohs was banned from Wikipedia, that means he also needs to be banned from Yahoo! Answers. The bastards have gotten him kicked off as both "MyWikiBiz" and "Try MyWikiBiz," the latter within days of the account being signed up. Supposedly Gregory Kohs uses multiple accounts on Answers, but no doubt the hypocritical Nihiltres and Coffee do so too, and on Wikipedia as well (in fact, they might be the same person).
Much more importantly, Gregory Kohs violated the unwritten rule of Wikipedia: You shouldn't criticize Wikipedia, which Nihiltres and Coffee and their various apologist sockpuppets on Answers wish to have extended to Yahoo! Answers. The reason this is important is that so many people turn to Answers to ask whether Wikipedia is reliable or not. There needs to be someone there to tell them that no, Wikipedia is not one bit reliable, and point them to the websites that tell the truth about Wikipedia, like Wikitruth (obviously), Wikipedia Review, Wikipedia Watch, MyWikiBiz, this blog, and even respectable newspapers of record like the New York Times and USA Today.
