So from my understanding, I can block an instance which prevents it from showing in my feed.
However, if the instance I post to (.world) is not blocked on the receiving instance’s end (Meta), they will still get my post (unless defederated)?
If so, doesn’t that open up the idea that Meta will be able to scrape and take ALL the data from ALL the (still federated) instances’ posts that are not blocked by the Meta instance(s)? How can I protect my information from Meta while still being federated, or is that not possible?
If you post something online, it is public and you have to assume someone or even everyone has already scraped and harvested the data.
It has always been like this.
If you come from an incumbent social media platform, perhaps you never got yo experience this lesson for yourself. But that data has also been harvested. They just gave you a bit of illusion of privacy.
The only thing online that is private is E2E encryption directly with a party you trust, and only if you are the only ones with a copy of the keys.
The benefit now is that one company can’t get exclusive access to your public data. It’s open to anyone that wants it.
