This is not about "rewards"

Censorship Defined

The -->suppression<-- of words, images, or ideas.

Downvoting a post makes it less visible, gets less views, gets less comments, also gets less rewards.

Suppression = Censorship.

Hive has censorship built into the protocol, called downvoting.

Many people have spread the word Hive is censorship resistant, it simply is "deletion resistant". Censorship is built in. If you keep getting hung up on that word, realize that that's the dictionary definition that Censorship = Suppression and has been that way for hundreds if not thousands of years. That is the real defintion and we aren't going to pretend the defintion was changed to mean something else.
