Schablon:Bots

This is a template for pages to specify whether or not they want visits from any bots, most bots or specific bots. This can be used to easily and explicitly opt-in or opt-out of unsolicited bot posts to user pages or to cause maintenance bots to avoid certain pages. Explicitly opting-in has the advantage of possibly receiving useful changes or targeted posts that might otherwise be skipped by the bot assuming a default "opt-out" behavior. These templates should be used mainly on the "User" and "User talk" namespaces and should be used carefully in other spaces.

Users should be aware that by opting-out of bot posts, they will not be notified of matters relating to material they have edited or uploaded, which are tagged or scanned by bots per policy.

In particular, in the encyclopedia spaces:

Avoid using the template as a blunt instrument
Address the root problem with the bot owner or bot community
Remove the template tag once the underlying problem has been resolved.

Syntax:

{{nobots}}                Ban all compliant bots (shortcut)
{{bots}}                  Allow all bots (shortcut)

{{bots|allow=<botlist>}}  Ban all compliant bots not in the list
{{bots|deny=<botlist>}}   Ban all compliant bots in the list

Where <botlist> is a comma-delimited string of bot usernames (AWB can be used for all AWB-based bots):
  {{bots|allow=HagermanBot,Werdnabot}}
  {{bots|deny=AWB}}

<botlist> can also be "none" or "all" as in the following examples:
  {{bots|allow=all}}      Allow all bots
  {{bots|allow=none}}     Ban all compliant bots

  {{bots|deny=all}}       Ban all compliant bots
  {{bots|deny=none}}      Allow all bots

Bots are not bound to observe the nobots tag, it will depend on their functionality, their owners and their terms of approval. The bots which currently support exclusion are listed at exclusion compliant bots.

Notes

List of some interwiki bots

SieBot,A4Bot,AlleborgoBot,Thijs!bot,YurikBot,Tsca.bot,Eskimbot

Implementation

Pywikipediabot supports bots and nobots since r4096. The templates may be ignored using a parameter.
Since version 3.2.0.0 AutoWikiBrowser fully supports {{bots}} and {{nobots}}. Additionally, pseudo-username AWB can be specified to ban all AWB-based bots from the page. However, AWB has an option to ignore these templates.
