Wikibooks:Blatant Vandal Blocking Policy

Blatant vandal accounts or IPs shall be indefinitely blocked on sight, without warning or notes on the user talk page. By blatant vandal we mean those who add obviously offensive materials and/or images to pre-existing Wikibooks modules and/or new pages.

In the case of accounts, checkuser shall be used in all cases of such vandalism, and if no good faith edits are found corresponding to any related IP addresses, those IPs shall also be blocked indefinitely. Administrators should monitor Category:Requests for unblock in order to prevent any unintentional harm.
