@danielsaori this bot is a neat idea. However it has taken to sweeping up some qualifying posts from a spammer that likes to use stolen posting keys to upvote their posts and comments with hundreds of dusty votes. Some people have been countering those votes to just below the threshold but then dustsweeper brings them back over it.
These are the accounts they are currently using for spam:
