1. We haven't had any problems with comments being arbitrarily censored. If someone mutes you, you can't comment in their threads. It's like someone in real life no longer inviting you to the party at their house. Why would you want to go to someone's party that doesn't want you there anyways? It has NO EFFECT on you being able to go to the rest of the party's. Bad analogy? Probably. Point is, we've been at this for years and we've had literally 3 users that have complained about muting and honestly.... they were extremely rude and the vast majority of the site muted them. They were essentially trolls. But, if a function is abused and no longer serves the purpose of our site, which is to foster a place for thoughtful discussion, we will definitely re-examine it. We aren't set in stone with our functionality, but we are set in stone with our vision for what drives our decision making.
2. Yes regarding the servers.
