I am the publisher of Wikipedia, We Have a Problem.
I've detailed a three year case study investigating harassment that occurs in Wiki Wars through personal experience
I also have two other WikiMedia accounts which were connected as my Wikipedia accounts.
These are Tumbleman and SAS81
Both SAS81 and Tumbleman have been banned indefinitely from editing on Wikipedia. Details of that tragedy are found on Wikipedia, We Have a Problem.
I am also a developer of a consensus building platform called aiki.wiki
