The fediverse is a privacy nightmare
blog.bloonface.com
ActivityPub, the protocol that powers the fediverse (including Mastodon – same caveats as the first two times, will be used interchangeably, deal with it) is not private. It is not even semi-…

TLDR: While Fediverse won’t directly serve you ads, anonymous bad actors other than Meta can save, redistribute, and even dox you for any information you post here. Anything you post here can/will remain forever on some malicious instance that doesn’t honor deletion requests. So be careful!

    Wait…the posts i send are “stored” on other instances? Inthought they were stored on just one and just accessed by the others? There shouldbe no need to delete from other instances. Once the post is deleted from ist home instance it wont show up on others anymore (because it was never stored there). Am i misunderstanding this? Like most, im new to Lemmy amd still figuring things out.

      Each remote instance stores the posts from every other instance’s communities, from the point at which the first person viewed (…or subscribed to…?) that community on the remote instance. That way the instances are less dependent on each other’s uptime and can optimize their queries, giving a better user experience.

      Btw. this also means that there will always be some delay before posts/comments from one instance show up on another.
