Update: So far many of the responses point out that if you post anywhere on the internet you are prone to this issue, i.e. even if you delete something someone may have copied it etc.
I do believe this is different. Yes, we are always at risk from malicious actors, but usually when using social media we can operate under the assumption that the delete button works. That is not the case for ActivityPub. Even without bad actors, your content may not be deleted. I think it's safe to say that this is an unappealing issue for most potential users.
Not at public sites. There's several websites that mirror whole reddit where you'll find plenty of deleted posts and comments. There's Twitter archives as well that keep copies of all kinds of accounts and posts.
You may have better chances in semi-public social media like Facebook where you have to be logged in to see anything. But you really can't operate under that assumption as long as you're on public social media.
I don’t actually think it’s safe to say that. I suspect that most people wouldn’t be very concerned about ActivityPub’s “best effort” federated deletion. But without actually polling people, I don’t think that either of these theories holds enough water to call “safe to say.”
Sorry I forgot to address your point - migrating people to a more technical setup would be a challenge in itself, but then informing them that deletion across servers isn't guaranteed would likely give them cold feet.
FWIW, it’s fairly rare for a deletion to not propagate. And I’ve yet to come across a rogue instance intentionally refusing to honor deletions. If we did, our instance would defederate from it.
Good point :)
I'd hazard a guess that ActivityPub users are a small portion of the population, especially considering the people I'm thinking of setting a server up for are Facebook users in a medium sized town - mostly people over the age of 40 who only started using social media in the past ten years.
It's no secret that onboarding is a barrier to entry for Mastodon for example, and even then most people likely haven't even heard of it. I am the only person on any of my social circles who is aware of it.
