And just to end on my original theme. I think you really should seek a better understanding of how to enable a "closed by default" model on your mastodon instance. If you're concerned enough about your privacy to go yelling at random people, then it's reasonable for you to go do the work to wrap your head around that. Because no one else is actually incentivized to do it for you. Again, that's what the fediverse is. Nobody is in charge.
