We don't want to claim something so strong as the first of this text,
because the mutee can still guess that they have been muted if the
muter suddenly starts completely ignoring messages, especially PMs.
But this framing is better in retaining the perspective as you.
We use styling same as that of the number shown for overflow
(e.g "+3") which has a gray background.
To keep these avatars up-to-date, we need to rerender the
recent topics view after receiving a `muted_users` event.
Also update the user documentation to mention this detail.
We deliberately avoid mentioning "recent topics" because
this applies to mobile too.
Also link to it from the API documentation page,
other help pages, and the confirmation dialog for
muting a user.
