Since its launch in January of 2001, Wikipedia has been the target of waves upon waves of criticism. At first most of it was warranted. The pages of the free crowd-sourced encyclopedia contained a great number of factual errors, making it easy for established encyclopedia brands like Encyclopedia Britannica to throw shots. Teachers and professors forbade their students from using Wikipedia as a source in their work. The tide began to change, however, as Jimmy Wale's project grew, and the editing and contribution system he put in place, one which allowed anyone with some free time to lend a hand, became stricter and more refined. Independent studies began to show that Wikipedia's information was virtually as reliable as for-pay encyclopedias, giving credence to Wale's dream to provide all of the world's information for free to whoever wants it.

However, the same "for the people, by the people" aspect that makes Wikipedia so remarkable is the same reason why people still look at it with a side-eye. Because nearly anyone can contribute, we've seen numerous pages flooded with wrong information, derogatory slurs, and funny images. Wikipedia calls it vandalism. To combat this, the not-for-profit has taken measures such as permanently locking pages. We're sure you've heard of a celebrity's page being changed. Most recently, it was Brandon Knight's after he was posterized by DeAndre Jordan. There's a bunch more. These are the 50 craziest we could find.
