Stupid question, but I thought you click the sidebar, and the three options were “join/leave, post, and block”.

But now, the ONE time I want to block a community, I don’t see the option. So I go to another community, just to see if it looks different. It doesn’t.

The communities now only have join/leave, and post. No block.

Edit: Problem solved for me. Should I leave this post up for any future people who ask this? Or should I delete it so future other people don’t try to answer a solved question?
