What was surprising was just how easy it was. We started with minor edits in small articles, just adding our own name to some list of notable achievers.
Then, due to competition, we would add an entire paragraph that fabricated an event. Like adding ourself as a conquistador of some made-up novohispano population in some made-up location.
Imagine how compromised wikipedia must be by people with agendas more lofty than uni students passing some time.
Hell, just the other day I removed "See Also: Donald Trump" from one of the major fallacy articles. The history showed that the scathing political commentary was up there for over 8 months and nobody cared.
