I've never used bluesky over Tor, so I'm unsure of any PDSes that explicitly allow Tor connections, but I would assume most of the independent ones would at the least be slightly less aggressive with this kind of moderation. My best advice for finding a PDS overall is just to ask your friends, because you probably know someone who's on an independent one, and they'll probably be able to point you toward how to sign up on it, too.
