As it says in the title, trying to report a post returns error 400.

I've yet to make an account on Mastodon and I'm wondering, how good are its consistency guarantees? Do posts get lost? Will they eventually get to all federated instances?

From my Lemmy experience, posts do get lost here, from time to time. Is it the same on Mastodon?

Think about it - all the most easily extracted fossil fuels, the stuff near the surface, are already exhausted. And, to transition to sustainable energy, you have to bootstrap manufacturing with fossil fuels, since mainstream sustainable energy requires photovoltaic cells and controllers and electronics.

It looks like the lack of persistent storage for the federated activity queue is leading to instances running out of memory in a matter of hours. See my comment for more details.

Furthermore, this leads to data loss, since there is no other consistency mechanism. I think it might be a high priority issue, taking into account the current momentum behind growth of Lemmy...
