As bots can make many edits during their run, their edits can overwhelm the recent changes list, making it difficult to see and respond to edits by human users. For this reason, bots that have been tested and approved by a wiki community can be given a bot flag. A bot flag is a setting in the MediaWiki software that hides bot edits from the recent changes list. Bot edits can always be revealed by clicking "Show bots" in the Recent changes header.
