I'm not talking about one or two whale downvotes. I am talking about downvote harassment which means that an account with a very large amount of SP is downvoting nearly all of your content continually to try and prevent your message from finding an audience in the Steem community.

Not only is that possibly illegal for US residence to do, since that is intentionally seeking to stifle someone's free speech. But if someone's business was completely built around the Steem ecosystem and the flagging account kept downvoting your content consistently it can be very possibly proved as malicious intent to harm that person's business.

It is not just about the loss in STEEM/SBD rewards, but also in customer acquisition and brand reputation.
