The AbuseFilter MediaWiki extension allows privileged users to set specific controls on user activity and create automated reactions for certain behaviors. It was first enabled on English Wikipedia on March 2009[1] and subsequently enabled on all public Wikimedia projects. Changes of the default configuration may be made on request.[2] Access to abuse log is restricted. Please update the following table when you request the abuse filter to be enabled (the local Special:ListGroupRights page can help).

Global abuse filters were subsequently implemented and are set and operated from Meta-Wiki. These global filters apply to small[3] and medium[4] public WMF wikis, and those large wikis that opt-in.[5] The stewards and meta administrators are able to set global abuse filters.[6]
