Blocking a user should hide your messages and mute you for them in servers

I wish that the block feature could stop blocked users from reading the messages you send, as well as prevent them from hearing you in voice channels. I'm sure there are many others like me who don't want their safety infringed just because they want to send messages/join voice chat in a server but a blocked user happens to be in the server as well. Blocking direct messages isn't enough.
