Test Wiki:Bots
From Test Wiki
Bots are accounts that perform automated or semi-automated tasks. A bot flag hides its edits from RecentChanges, among other things. While this group can be tested with, please remove it from a human account when done testing, and restore it to a legitimate bot account when done testing.
Bots are able to make edits very rapidly and can disrupt Test Wiki if they are incorrectly designed or operated. For these reasons please do only use bots, if you know what you are doing and keep an eye on the bot's contributions.
This is one of the six default MediaWiki user groups, see mw:Help:User rights and groups.
