Bots are usually operated by one of the wiki's admins, and the bot flag has to be requested first.

However, it is possible for a bot account from another wiki to run a script on your wiki. I'm not sure if that bot gets identified as such in Recent Changes, though. It could be murder on Recent Changes. It's technically also possible to run a script on a regular account, but that practice is somewhat frowned upon.
