Complex vandalism at Joan of Arc - despite being a featured article, this page has seen intermittent problems with complex vandalism and POV pushing. Most of the more serious problems appear to originate from a single person - here called Editor X.
Editor X uses a randomized IP from an AOL account that originates in Reston, Virginia. User:Switisweti, User:Vyran, and User:Durova tracked occurrences of disruptive edits that followed similar patterns. A log of these IP addresses is available at User:Highest-Authority-on-Joan-of-Arc-Related-Scholarship/AWilliamson sock puppets. As the title suggests, these three editors suspect that this IP range represents the same person who formerly edited as User:AWilliamson and User:Center-for-Medieval-Studies. The same editor was active again in April - June 2006 and possibly at other times.
