Our previous thread wasn't federating properly and most instances were only getting the first 2 of 14 posts. We had to post it again a few times trying to resolve the problem.
The last configuration change and Mastodon server restart appears to have resolved it, if you can consider disabling an important anti-abuse feature resolving it.
We'd appreciate if people who boosted the original thread or the 2nd/3rd attempts at redoing it would undo that and boost the current working thread instead.
