Manual:Block and unblock/ja

Sysops can block and unblock IP addresses (and registered user accounts if username blocking is enabled) from editing, uploading files, moving pages, and, if they have been granted such rights, protecting/unprotecting and deleting/undeleting pages. It is important to remember that blocks are preventative, rather than punitive.

ブロック
ブロックは、特別ページ Special:Block にあるフォームで適用できます. There are several steps to applying a block:


 * 1) ブロックする IP アドレスまたは利用者を指定します.  ブロックしたい IP アドレス、またはブロックしたい登録済み利用者アカウントの利用者名を、フォームの「」欄に入力します.  存在しない利用者もブロックできることにご注意ください. そのため利用者名が正しいことを確認してください.  IP アドレスの範囲もブロックできます. 手順は  を参照してください.
 * 2) ブロックの期間を指定します.  「」というラベルのドロップダウン ボックスからあらかじめ定義された期間を選択できます. 「その他の期間」欄にGNU の標準書式を使用してカスタム値を入力することもできます.  期間を「無期限」にすると、管理者が IP アドレスまたは利用者を管理者がブロック解除しない限り、ブロックが期限切れになりません.
 * 3) ブロックの理由を指定します (省略可能).  この理由は、ブロックされた利用者がページの編集を試みた際にその画面に表示されます.

ブロックを適用するには「」をクリックします. ブロックはすべてブロック記録に記録され、現在有効なブロックはすべて有効なブロックの一覧に列挙されます.

さらに、Special:Block でのブロックしたい IP アドレスまたは利用者アカウントの手作業での入力について、IP アドレスまたは利用者アカウントの「利用者」または「利用者 トーク」ページを閲覧している際にサイドバー内のツールボックスから「」リンクをたどることでも手作業での入力を回避できます. 最近の更新の一覧またはページの履歴で、IP アドレスまたは利用者アカウント名の次の「」リンクをクリックすることでもブロックできます.

ブロックのオプション
Several extra blocking options were added in version 1.8 of MediaWiki, which are enabled by checking a check box on the blocking form.


 * 匿名利用者のみをブロック (別名 ソフトブロック): This option changes the effect of a block when blocking an IP address. When it is enabled, the block will only affect anonymous users editing from that IP address; registered users editing from that IP address will not be affected. The option has no effect on a block of a registered user, but does on an autoblock caused by it.


 * アカウント作成をブロック: This option changes the effect of a block when blocking a user or an IP address. When it is enabled, the registration of new user accounts from that IP address will be disabled while the block is in effect.


 * Automatically block the last IP address used by this user, and any subsequent addresses they try to edit from (also called hardblocking): This option changes the effect of a block when blocking a registered user account. When it is enabled, the IP address most recently used by the account, and any IP addresses that the account subsequently attempts to edit from will be automatically blocked.

ブロック解除
An IP address or registered user account can be unblocked via the list of active blocks. Find the IP address or registered user account you wish to unblock in the list (you can enter the address or name in the "search" field to help you find the entry), and click the "Unblock" link displayed to the right of the block's expiry time.

This will lead you to a confirmation page. Enter the reason for unblocking (optional) in the "reason" field, and click "unblock this address" to remove the block. All unblockings are recorded in the block log.

Note that if a range is blocked, then the unblock must cover the whole range to be effective. Attempting to unblock an individual IP address in the range will not be effective.

Effects of being blocked
Blocked users may still read pages, but they may not create, edit or move pages, or upload files. Users with certain other user rights will not be able to use those rights when they are blocked. For example, users with the rights to delete and undelete or protect and unprotect pages will not be able to do so when they are blocked. However, users with the rights to block and unblock users will still be able to do so when they are blocked, including any blocks on their own account.

Users who are blocked and attempt to edit a page (or move a page, or upload a file) will see the "user is blocked" message informing them that they have been blocked.

If the autoblock option has been enabled with respect to a block, and the blocked user attempts to edit (or move a page, or upload a file), the IP address being used by that user will also be blocked.

Configuration settings related to blocking
The configuration options below can be set in and can be used to enable or disable certain aspects of the blocking interface.


 * - controls the ability for sysops to block usernames. これの既定値は true です. If a sysop tries to block a registered user account and this setting is not enabled, then an error message will be displayed, informing the sysop that the "IP Address does not exist".
 * - controls the ability for sysops to block ranges of IP address. これの既定値は true です.
 * - controls how many seconds need to pass until a block on an "autoblocked" IP address will expire. The default is 86400 seconds, which is the same as 24 hours (one day)
 * - controls whether or not a blocked user is able to edit their own user talk page. これの既定値は false です. The ability to disable the ability of a blocked user to edit their own user talk page, when this variable is true, is an option available in Special:Block.
 * and the blockemail user right control the ability for sysops to prevent users from using the Special:EmailUser interface.  の既定値は true です.
 * - controls if blocked users will be allowed to login. これの既定値は false です.
 * The hideuser user right controls the ability for sysops to prevent a blocked user from appearing in the block log, the active block list, and the user list.
