@broombot is for the community to flag bot comments currently considered "service" or "advertising" comments by @steemcleaners & spaminator.
I don't have the time or the SP to get involved with insults or disputes. None of which is part of @spaminator, steemcleaners, or @mack-bots scope.
By "double-owner" account you mean a single person that signs up or gains control of 50 or so accounts delegated to by the @steem faucet, then that is something for @spaminator.
Thanks for the explanation @patrice
