According to Wikia, "A bot is a piece of software that makes automated edits on a community and also helps users to make automated or semi-automated edits that would be too tedious to do manually. Bots are most often used to make repetitive edits to many pages." Bots may be temporarily blocked if they begin to malfunction. You can read more about bots here.
