Blocking is the method by which administrators may technically prevent users from editing My English Wiki. Blocks are used to prevent damage or disruption, not to punish users. Blocks sometimes are used as a deterrent, to discourage whatever behavior led to the block and encourage a productive editing environment. Blocked users can appeal their blocks by making a statement on their talk page. Except in cases of unambiguous error, administrators should not undo other administrators' blocks without prior discussion; see below.
