PieFed has a dizzying array of settings and options that instance admins can tweak. Most of them have obvious and sensible default values but some of those have been a bit controversial, especially to do with what gets blocked by default. In this post I explain what those are and how they can be configured.
Yes that list should really be checked and old offline instances removed, etc. Although any chance I get to give Zuck the finger is hard to resist.
I was always iffy about preemptive Threads defederation. If federation really worked we could tell folks on Threads that our instances are much nicer, ad-free and still capable of following Kim Kardashian or whoever is using Threads. A bit of a moot point now anyway.
