@f4grx@snarfed.org@snarfed.org congratulations, you don't have to have anything to do with Bluesky. But bridges are a normal part of federation, if this feels threatening I strongly recommend you read up on how ActivityPub (the protocol used by Mastodon) works, how bridges work, and the history of bridges in the fediverse.
Odds are you'll never see any personal impact from this whatsoever unless you make friends with someone who's on Bluesky or share something that goes super viral (in which case you'll probably be thankful for this because you have zero control over screenshots, but through the bridge you'll still have access to blocking, deleting, and editing of posts)
