See e.g. https://piefed.social/communities?search=forward - there are 2 communities listed there, both go to the same place if you click them, and that place has no posts from the last 3 days.

It almost looks like the existence of the second version of that community - changed mere seconds ago at the time of my writing this, except again, when you click the link it doesn’t show anything new for several days - is soaking up all the new posts, but since it is inaccessible by the normal means those new entities cannot be accessed.

This is my favorite spot in the Fediverse, so I hope it is addressed soon! That community in particular is doing great work to make the Fediverse fun & welcoming to come to by all us nerds:-).
