Users can be blocked for many reasons. If you are blocked, you will not be able to edit.
You can be blocked for
- Breaking Wikibooks policies
- Adding pages that are copyright violations
- Inappropriate user name
Users should be warned with appropriate warning templates before administrators block them, but administrators can block a user at any time if they are being intentionally disruptive or violating other policies. All administrators who block users must have a working email address in their personal settings so they can be contacted by a user affected by a block if necessary.
If you feel you have been unfairly blocked, please contact the person who blocked you. Tell them what IP you are using. This information is shown on the page that tells you that you are blocked.
Contact details for administrators are listed on the Administrators page.
Most blocks should be for 24 hours.
Vandal bots should be blocked as soon as possible. If you need help to stop an automated vandal, ask a steward in the the #wikimedia-stewards IRC channel or at meta:requests for permissions, where someone else may be able to report it to the IRC channel. A bot may be attacking other Wikipedias too, which is why you must report it. See m:vandalbot for more details.
Administrators should block anonymous proxies. This was talked about on the mailing list. You can set the timestamp for "1 year".
Try not to block ISP proxies. This sort of block would affect lots of people.
