这是一个好问题：

@blocktrades 大佬的帖子中有如下内容：

How is blacklisting different from muting?
Muting an account means you don’t want to see the account’s posts and comments. Most frontends honor muting by preventing those posts from being displayed when you view the site.

Blacklisting an account implies you think the account is doing something wrong, and is intended to be used as a way to warn others that you think they should be careful when dealing with that account.

我理解mute就是不想看这个用户的帖子。

blacklist的用途可能更多一些，比如点赞机器人说不给这部分用户点赞，或者禁止对这部分用户转账，或者也可以单纯地不显示这部分用户的内容，等等等。或者还可以更狠一些，看到这部分用户的内容，机器人就去踩。😳总之用处多多。
