QuietBot is a bot owned by Quietust. It is run manually, which means all changes that it makes are approved by Quietust on an individual basis. This does not mean that all edits it makes will always be perfect, but most should be caught ahead of time.
If you would like QuietBot to perform a repetitive task for you, leave a message on Quietust's talk page and he will see what he can do.
In the event that this bot somehow manages to run out of control and starts performing numerous incorrect edits, simply leave a message on its talk page and it will immediately stop whatever it is doing.
