Not familiar with moderation capabilities on PieFed, but something that can aid when moderating is having RSS tracking your communities. Even if the post gets deleted, if the RSS reader fetched the post in the time frame before that, it gets stored in your reader’s (preferably persistent) cache.







For the Instagram people, if they’re also using Threads, poke them to enable ActivityPub. Several medium/large instances defederate, but it’s an entry point for them.
Also, don’t be forceful and try not to pass a sense of superiority. Apply pressure when you see opportunities, such as if they complain of a platform, how a given alternative solves that, but know your boundaries. And all the while, be patient, for it could be a years-worth endeavor.
