This template is used to notify a user that they have been blocked. It informs them of the reason for their block and describes the steps they can take if they wish to continue editing. It has been carefully designed based on guidelines by the user warnings project.

Please refer to the index of message templates before using any template on user talk pages to warn a user. Applying the best template available for your purpose may help reduce confusion from the message you are sending.

Note: Only administrators can block users; adding a block template does not constitute a block. See RFAA to request that a user be blocked.

Please remember to substitute the template by using {{subst:Uw-blockindef}} rather than {{Uw-blockindef}}. (Although this template must be substituted in the user talk page, it has also been designed to display properly when substitution is not possible.)

To give greater detail to your message, you may specify: the block duration, a specific reason for the block, and to auto-include your signature.

{{subst:Uw-blockindef|anon=yes|reason=For a different reason|notalk=yes|page=Targeted page|sig=yes}}

• If not blocking an anonymous user, omit the anon parameter.
• Include the page parameter to refer to a page on which the conduct supporting the block occurred.
• The notalk parameter should always be omitted unless the user cannot edit their own talk page.
• The optional for parameter can be used if the word "for" before the block reason doesn't grammatically work. For example, if for=per is written, the block notice will say "blocked from editing per". Don't use this parameter if you don't want to change the word "for".

• The message for the unblock process can be found at Template:Uw-block/unblock.
