but bad actors can just migrate to a new one, or spin up a new hostname.
Then you defederate from it too. I just went through some instances list, some servers have been defederating Mastodon instances like crazy
Then you defederate from it too.
Okay, let me create an account on mastodon.social and use it to scrape content from every other instance.
Better yet, let me create an account on “i-want-privacy-in-a-public-internet.example.com” and access the federated timeline directly, then I can go and push the content from everyone into this discovery service.
What are they going to do? Unless they go to the point of asking for physical evidence behind the person asking for accounts and/or only give invitations to people they already know, and *completely shut down their own servers to the outside world, they will never be able to avoid data leakage.
And if they do get to do any of this, then what is the point of using anything based on ActivityPub? They will be better off by just using any of the existing group chat servers like Discord (or Matrix/XMPP if they still care about FOSS.)
The point we were discussing was not data leakage, it was the inability to defederate from a huge instance which would overflow the number of users, similar to the way people imagined what would happen if Threads federated, and Lemmy is suddenly overflown with people usually on Facebook.
It’s not a bad thing per se (anyone can make their own opinion), but not having even the option to defederate is the issue.
No, admins might think of defederation as a way to avoid interaction with larger instances, but in the case of the bridge it was mostly regular users crying “I don’t my content going in a place that I do not control”, with “lack of opt-in” and “this violates GDPR” being the main reasons cited to be against it.
With Threads is the same thing. The whole thing with users asking their admins to block threads is not because they were worried about Threads pushing too much to the smaller instances, but to block Threads from mining data from the Fediverse to their profit.
