This user account is a bot operated by ShakingSpirit (talk). It is used to make repetitive automated or semi-automated edits that would be extremely tedious to do manually, in accordance with the bot policy. This bot does not yet have the approval of the community, or approval has been withdrawn or expired, and therefore shouldn't be making edits that appear to be unassisted except in the operator's or its own user and user talk space.
Administrators: if this bot is making edits that appear to be unassisted to pages not in the operator's or its own userspace, please block it.

ShakingBot

ShakingBot is a fully human-assisted bot which is used by ShakingSpirit to make minor fixes to articles that would be drudgery to do by hand (including disambig repair, stub sorting, typo-fixing, etc). WP:BOT states that human-assisted bots do not need to go through bot approvals, and so ShakingBot is both un-approved and un-flagged.
ShakingBot was originally intended as a bot which checks an article's external links to ensure each link is alive and working. If it found a bad link, it would post a notice on the article's talk page, and tag the link. This is being put on hold after several suggestions and ideas from other Wikipedians which ShakingSpirit would love to include, but currently he doesn't posses the knowledge of Python required to code them right now. It's fully expected that one day ShakingBot will fulfill this function.
