I have mixed feelings on this. I think this will help in the future when we have more users and spammers are running rampant. This type of feature helps to easily mute them. However, I fear that mute lists can be abused and could be used to effectively shadow ban people. I don't want to go down that route.
There will always be those who abuse any function... but it is voluntary, you should be able to subscribe and unsubscribe, if you have people like gods and you only subscribe to their lists because of who they are, it is very likely that what you say will happen... power corrupts
& people are simps, so it will happen but that's fine by me. Id rather have a group of 5 people interact with than ingest the absurd weakness & stupidity of the herd.
