How does Cohost behave if someone makes an unwanted reply to your post, and you block them? Does the reply just stay there as-is?

I'm 100% behind this one, it should be a given I'd think.
I have found that also you will continue to get phantom notification for it too. The number will keep going up, but if you click through, nothing shows in the list because it's notes for a post you can't see now.
