@snarfed.org @activitypubblueskybridge @fedidevs @fediversenews A lot of people are upset about this but ya'll know, straight up, if your feed is live & people not auth'd can read your server feed you *don't have privacy*. Mastodon and the fediverse in general never said anything about expectations of privacy.
Snarfed here could have been a bad actor and never told you anything and as far as I know it's in the clear.
If you don't like it, block the bridge and move on.
