If you visit https://lemmy.world/post/1181467?scrollToComments=true and check the post, the tiny comment icon under the post says that there are 5 comments. Checking the post however, you can see that there are only 3.
Is this some Lemmy bug, or does Lemmy shadow-remove comments like Reddit?
I noticed lots of posts were missing, like some communities were completely empty but in the sidebar it showed as having dozens of posts. I went to settings and made sure I had English and undetermined selected and suddenly they all appeared.
Not sure if that would be the same for comments but worth trying.
