What? You don't even need to understand how Mastodon works in depth to realize that sending a post to 500 different servers owned by completely different people in completely different jurisdictions is going to make it harder to delete later.
Sure -- but it also makes it harder to verify. That's my issue with Bluesky, perhaps I'm thinking like a lawyer. ATProto's most touted feature is also its biggest danger. A post on 2 servers thats hashed/verified (and perhaps admissible in court) might be more dangerous than many more rando Mastodon servers.
Seems like the solution is to either not incriminate yourself online or get plausible deniability with a pseudonym.
AGAIN, we are way past SIMPLE SOLUTIONS like this. We have enough data and information to be able to see the potential for harm that we can mitigate through smart policy without falling back on this simple argument.
Not being able to trust the integrity of the data on the Mastodon network to the point it's not admissible in court is not a good thing for Mastodon. If this is really true, I'd say it's a completely failure of the most fundamental concepts of information technology.
