Well the way it works is that your instance broadcasts the posts to all of the other instances that it thinks might want to see them, so copies of the post live on all of those other instances, and they are free to do whatever they want with that content.

When you try to delete something your instance sends out a message to all of the other instances requesting politely that they delete from their own storage as well, but there's no way to make sure they actually do.

Basically, everything you post to this platform should be regarded as posting to the public with tags politely requesting privacy. And that might be good enough for most people, but I just want to make sure people are aware of that as they use the platform.
