If a wiki is receiving heavy amounts of vandalism, you can get a temporary protect site (disallowing anonymous users from editing). In the long term, the Abuse Filter extension is the better bet. The AbuseFilter is an extension that allows you to set conditions. If those conditions are met, you can choose what happens then (usually stopping the edit from happening). Special:Contact to talk to staff about either.
