Any user may request a block on an Admin's message wall for major incidents of vandalism or disruption. Users requesting blocks should supply credible evidence of the circumstances warranting a block. Administrators are never obliged to place a block and are free to investigate the situation themselves. Because blocks may be reviewed and appealed, it is often important that the blocking and reviewing administrators each communicate with and take care to inform the other.
Blocked users can appeal their blocks by making a statement on their message board. Except in cases of unambiguous error, administrators should not undo other administrators' blocks without prior discussion; see below.
