Why can't I block communities I am banned from? (solved)

Another reddit.world community got mad at me for saying "death to US" and now I'm banned. That's fine! But why can't I block them now? I am forced to see their posts every time I go to /all and can't comment or vote, so am effectively forced to view content without any ability to interact.

I don't want to see their posts and should be able to block them from my /all feed

Here look! When I'm not banned there's a clear option to block the community:

But after being banned I now can't block the community, I'm forced to keep seeing it in my feed!

SOLVED: From the user settings page there is a tab for Blocks next to the tab for Settings, and you can manually search for the community you wish to block in a search bar. That worked, even if the UI on the community page was messed up by the block message.
