Thanks, that cleared it! Would be a cool feature to be able to unhide blocked comments when curiosity gets the better of me. But I can also live without it now that I know ;)

Related topic, though not the same :

Voyager app has a big blue button on the posts page, that leads to the temporary display of hidden posts (not comments).

This is really useful for many purposes, I guess. for me it is useful, because I have some kind of inbox zero approach. I swipe away (hide) post that I have seen and do not want to see anymore . But sometimes I still want to see them again. Then I just press this button.

Would be cool for PieFed, too! This approach could be applied to posts, as on voyager, as well as on comments, as discussed in OP.
