Dear #TwitterMigration folks, an important tip on #privacy on the fediverse:
There is none.
This is a public medium; please treat it as such. Just as you have no privacy on Twitter (Elon Musk can read all your DMs), you have no privacy on the instance you’re on (your administrators can read all your posts).
You can set the visibility of a post but that’s a viewing suggestion, not a privacy guarantee.
Think of your posts as postcards, not sealed letters, and you should be fine.
@aral Is that really any different from any other social media platform? At least here I have a reasonable expectation that my data isn't being sold to corporations.
If you're concerned about your posts you can click on the globe icon below the message (may not be available on all instances) and choose from the list who can see your toot.
In the 90s people generally treated email as a postcard, but it became so useful to assume that email would be secure, so perception shifted to allow email to be used for more things.
Something you can access with just your browser can never be secure from the web admin's prying eye.
