@pixelpusher220 @noxypaws @snarfed.org @activitypubblueskybridge @fedidevs @fediversenews uh yeah, that's the whole point. This bridge acts just like a regular Fedi user and follows all the same rules. If the bridge can't see your posts, it can't do anything with them - and you have full control over how visible your posts are. You also have the option of adding a hashtag to your profile, defederating from the domain the bridge lives on, or contacting the dev for a manual opt-out.
Plus, as far as I can tell, absolutely none of this is intended to happen in a vacuum. The documentation I linked earlier explains that users who are followed via the bridge still get a notification that they were followed, just like they were followed by a regular Fedi account. You'll see the BlueSky user names of each user that follows you through the bridge, and you'll be able to block individual users from seeing your account through the bridge if you so choose (in addition to the options above).
You'll have the same control over who can see your content that you would with any other Fedi user.
I'd strongly recommend reading the documentation to get a better understanding of how this is intended to work when it goes live.
