Effects of being blocked ==
Blocked users and a IP addresses can still see all Wikisource pages, but the "Edit this page" link brings up a "[[MediaWiki:Blockedtext|User is blocked]]" page which explains the reason behind the block and gives information on how to request unblocking. This page includes the "reason" message supplied by the administrator who placed the block. Links and template includes all work as normal in the "reason" section.
The duration of the block depends on the expiry time that was entered at the time of the block, which may be "indefinite" or "infinite" (ie, until explicitly unblocked).
When a blocked user attempts to edit, the IP from which he or she is editing is "autoblocked", so that the user may not make the same edit anonymously or under a different user name. There is an internal autoblock expiry time variable, which is set to 24 hours, meaning that when a username is blocked indefinitely, their IP will be automatically unblocked 24 hours after he or she last accessed a page.
For admins and bureaucrats, being blocked also restricts their ability to use rollback, to delete and undelete pages, and to protect and unprotect pages. They can still add and remove blocks, and bureaucrats can still make someone a sysop.
