Handful of “highly toxic” Wikipedia editors cause 9% of abuse on the site, by Annalee Newitz | Ars Technica
“Perhaps surprisingly, approximately 30% of attacks come from registered users with over a 100 contributions.” In other words, a third of all personal attacks come from regular Wikipedia editors who contribute several edits per month. Personal attacks seem to be baked into Wikipedia culture.
The researchers also found that a large percentage of attacks come from a very small number of “highly toxic” Wikipedia contributors. Eighty percent of personal attacks on Wikipedia come from people who rarely make personal attacks. But a whopping 9% of attacks in 2015 came from 34 users who had made 20 or more personal attacks during the year. “Significant progress could be made by moderating a relatively small number of frequent attackers,” the researchers note. This finding bolsters the idea that problems in online communities often come from a small minority of highly vocal users.
