A mute button is the exact opposite of censorship. Censorship is when someone else decides what you can or can't see. The mute button will allow you to decide for yourself.
I also support a downvote option. While muting is a personal setting ("I don't want to see these posts on my feed"), downvoting could be part of the platform-wide ranking of posts.
Free-market ranking could be great: you vote up or down with your bitcoin. The number of satoshis tipped to the poster minus the number donated to faucet as downvotes determines rank.
That’s an interesting idea also!
