For an example of a biased and probably state-backed Wikipedia editor, see the example of Philip Cross. I very casually edit Wikipedia, a few times a year, and I within an hour of certain changes ran into this "individual". Cross is almost certainly a team of people, and they didn't fully remove my edits, but it was very clear that certain topics are heavily monitored and shaped.

> Political analyst and former UK British ambassador Craig Murray described the scale of Cross’s activities:
> Philip Cross” has not had one single day off from editing Wikipedia in almost five years. “He” has edited every single day from 29 August 2013 to 14 May 2018. Including five Christmas Days. That’s 1,721 consecutive days of editing. 133,612 edits to Wikipedia have been made in the name of “Philip Cross” over 14 years. That’s over 30 edits per day, seven days a week. And I do not use that figuratively: Wikipedia edits are timed, and if you plot them, the timecard for “Philip Cross’s” Wikipedia activity is astonishing if it is one individual.’
