While I agree that downvote abuse is completely unacceptable, I'm not sure that getting into a flagging war is actually furthering your goals or those of the steemit community. By creating this post, bernie has already made about $27 just by replying to your comments and self-upvoting. Until you are able to downvote every reply of his to zero, you're not "hitting him in the wallet," you're just adding to his ill-gotten gains. I'd advise not engaging him until you can do so without rewarding his bad behavior.
