Perhaps we do need better tools. Perhaps a user should be able to control those that can reply to them in some way. Perhaps the owner of a post should be able to make certain comments less visible regardless of their flagging power. Maybe we should consider what certain users are doing with the Spam as a form of DDoSing or other type of intentionally malicious behavior that should possibly be addressed in some type of administrative way. Perhaps witnesses should vote to silence certain users from a certain front-end. Since certain users are causing Steemit to crash for other users, it can certainly be argued that their behavior should not be shown on the Steemit front-end. Perhaps witnesses should do like congress does and just do a sort of vote of disapproval that may be seen as a sort of warning.
