* lệnh cấm có thể có kinh nghiệm nhưng thiếu cơ sở quy định.
Once you are convinced that a block is warranted, the recommended procedure for controversial blocks is:
# Check the facts with care.
# Reread appropriate parts of this blocking policy.
If possible, contact other administrators informally to be sure there are others who agree with your reasoning. The [[ Wikisource: administrator's noticeboard| administrators' noticeboard]], the IRC channel ([irc://irc.freenode.net/wikisource #wikisource]) and email are effective tools for this.
# Place the block, exercising due care in the wording of the "reason" message, and include a link to the user page of the user being blocked.
# Place a notice of the block on the [[Wikipedia:Talk page#User talk pages|talk]] page of the affected user, with additional rationale, outlining the facts and the part of the blocking policy you feel applies.
# Be willing to discuss the block with other Wikisourcers.
Block wars, in which a user is repeatedly blocked and unblocked, are extremely harmful. They are a source of frustration and disappointment to many seasoned Wikisourcers and tend to encourage further bad behavior on the part of the blocked user. Avoid them. If you disagree with a block, discuss the matter with the blocking admin and others, and try to reach a consensus, rather than unblocking. Bear in mind that the blocking admin is likely to know more about the background to the situation than you do.
