"Wikipedia on Tuesday unveiled a "universal code of conduct" aimed at stemming abuse, misinformation and manipulation on the global online encyclopedia. The new policy aims to thwart efforts to distort and manipulate content on Wikipedia, the largest online encyclopedia which is managed largely by volunteers using "crowdsourced" information."

The new code was released by the Wikimedia Foundation, the nonprofit that administers Wikipedia, expanding on its existing policies to create a set of community standards to combat "negative behavior," according to a statement.
