I think just links for help communities where users can ask technical questions and find answers would be enough. You don't know what your followers use, they can read the piefed community from a lot of places, you can follow it from lemmy or mastodon, so it's possible that piefed related help would be irrelevant for most of them. These kind of technical writeups are common in "main" or "meta" communities, where you can assume your users are on the same instance as you, as the topic of the community is the instance.
For general piefed help there is !piefed_help@piefed.social
