This is supposed to work and I've seen it work. But so many people complain about this that I think it must be bugged and doesn't always work. Maybe it doesn't work when the posts are on different pages.

Is that how it's supposed to work? I use the default browser client and I've never noticed it. I have seen duplicate posts (ie the same post from the same community) on different pages. Maybe that's why.
Just came across an example of exactly what I'm talking about in my suggestion. The first post was hidden via the front page, and the second post was seen afterwards.
Userpage showing both posts, with one hidden: https://lemmy.ca/pictrs/image/74c84b3f-43a6-4d69-a08c-d84927e8007e.png
Second, unhidden post still visible on All feed: https://lemmy.ca/pictrs/image/fbc655af-a3b8-4df6-87f6-84719d6e7d98.png
Maybe the complainers are using clients that don’t support the feature.
How can one block a post..?
The drop-down menu under a post provides the option to "Hide Post" or "Unhide Post", depending on its current state.

Wow, thanks. Not sure how I missed that all this time!
