The appropriate way would be to use Special:Contact and show Staff the issue. Also, if other people (assuming this bureaucrat didn't ban them all) on that wiki also agree, try to convince them to have a community vote to demote this guy, staff will certainly respond to that if you show them a community vote agreeing with you.
