The block function should work more like an actual block in servers

I'd much prefer if users you have blocked, if you share a server with them, are completely unable to see your posts, or any messages where you are mentioned by other members. Additionally, I think it'd be good that they cannot even tell you are a member of said server to start with. The blocking system only being that they cannot message you but can still see your posts allows for too much harassment in my opinion.
