ANSWER: Wikipedia vandalism [accept word forms; accept equivalent descriptions like defacing Wikipedia or trolling Wikipedia or making bad edits to Wikipedia; prompt on “vandalism” with “of what website?”; prompt on “editing Wikipedia” with “editing that is considered an instance of what action?”] (I feel obligated to clarify that AmaryllisGardener turned out to be a well-meaning teenager who received a lot of undeserved online hate, but it’s still amazing that one person who didn’t know Scots created over a third of Scots Wikipedia.)
