I’ve been using federated social media for a while now and I recently considered setting up an instance for my local community as a sort of Facebook alternative. However, as I thought about it, I wondered if ActivityPub’s deletion problem (i.e. if a user deletes their content on their server it doesn’t guarantee the content being deleted on other servers) is a fatal flaw. I worry that it would be difficult to secure buy-in from people if they were made aware of this issue, which they have the right to. It does make me wonder if the ATProtocol will be the better protocol if and when it becomes open source.
I’m curious as to other drivers users’ thoughts. While it is an issue that we may be happy to live with given the numerous other benefits ActivityPub provides, is it a flaw that will ultimately prevent wide scale adoption?
Yes, it should be explicitly mentioned, that deletion isn’t guaranteed. But I don’t think it’s a deal breaker. People should be aware that posting something publicly on the internet, must always be considered to be preserved into infinity.
If you post something publicly on Facebook, there is also a high probability that some web scrapers save your pictures and posts. Deletion does nothing there.
Btw ATproto is even worse. Pretty much everything is public there. https://docs.bsky.app/blog/block-implementation
