It's the dunk tank.
This is where you come to post big-brained hot takes by chuds, libs, or even fellow leftists, and tear them to itty-bitty pieces with precision dunkstrikes.
Rule 1: All posts must include links to the subject matter, and no identifying information should be redacted.
Rule 2: If your source is a reactionary website, please use archive.is instead of linking directly.
Rule 3: No sectarianism.
Rule 4: TERF/SWERFs Not Welcome
Rule 5: No ableism of any kind (that includes stuff like libt*rd)
Rule 6: Do not post fellow hexbears.
Rule 7: Do not individually target other instances' admins or moderators.
Rule 8: The subject of a post cannot be low hanging fruit, that is comments/posts made by a private person that have low amount of upvotes/likes/views. Comments/Posts made on other instances that are accessible from hexbear are an exception to this. Posts that do not meet this requirement can be posted to !shitreactionariessay@lemmygrad.ml
Rule 9: if you post ironic rage bait im going to make a personal visit to your house to make sure you never make this mistake again
The comments are something else, too.
Did you know that calling out bootlicking makes you effeminate, bucko? 
If I understand correctly, you can't see certain comments unless you unblock a community? If so, that sounds like a bug.
That seems to be the case, yes. Expanding comment threads in communities I've blocked doesn't seem to work.
Is this only affecting comments in the blocked commumity? Or is it affecting comments in non blocked communities?
Only blocked communities. It works fine if I unblock them.
I think I've had similar issues with not being able to expand when even one person in the thread was blocked.
