@Popehat I just checked his account... it is real.
But the context is that he feels mute is sufficient and gets you all you need. Block makes no sense since users can still view your posts via proxy/public view anyway which is the only difference between a mute and block.
He kinda has a point... what is block getting you over a mute?
Im not sure its about lack of perfection so much as uselessness. People can browse anonymously, so blocking achieves effectively nothing.
The difference is making another account to circumvent a mute is against the rules and would get the account banned. Browsing anonymously is allowed and encouraged.
Im not sure what my opinion is honestly... once could say allowing blocking breaks the ability to browse publicly and anonymously by requiring extra steps (you need to logout or use a private tab). So you gain nothing by having the feature, but also make a different feature (anonymous/public browsing) work in weird and unexpected ways.
