@hurgusburgus @snarfed.org as a fellow trans* individual: you're either probably not familiar with how bridges work or you are not using safe practices and taking things for granted.
There are already many bridges on ActivityPub to much worse parts of the fediverse and they're not making waves (if you think Bluesky is bad, you should see Nostr). If they start harassing a user you treat it exactly the same as you would someone showing up to harass you from a new Neo-Nazi Mastodon instance, you can either block the user or block the whole bridge (only downside of a bridge is that you can't really block by individual server on the other side, it's either block individual users or the whole bridge).
This also has absolutely no threat of legal challenges to go along with it, it falls under numerous legal protections. Let alone the argument will absolutely fall apart in court that someone would complain about easily blockable abuse on a public post.
In case you're not aware, because it seems a lot of people think a bridge is some sort of web-scraper... it's a translator between protocols. It's not scraping your profile and copying posts, it's translating ActivityPub requests to Bluesky requests and back.
