@evan I was responsible for how block and mute work on Twitter. Ideally, these are two separate tools with different functionality.

Block intentionally lets the blocker know that they’ve been blocked (when they try more interaction with you). It also stops syndicating your posts to them, hides your stuff from them, and removes you from their lists.

Mute came later and the main difference is that mute doesn’t let the mutee know that they are muted. It is you controlling your frame.
