lemmy.world still “has” content from beehaw before the block happened. you can still see it and interact with it, but anything you do on beehaw communities that you have copies of won’t get synced to beehaw, and thus can’t be seen by anyone else on the fediverse.

you shouldn’t be getting new posts from beehaw at all, other than comments inside of non-beehaw communities (such as in a kbin magazine where a beehaw user comments).
