Not sure if the following has been part of information and discussion around here.
Apparently there are several Nostr relays that bridge, with or without asking for permission, profiles to somewhere else.
In this link there is a csv file with known servers that can be importet into the server blocking list:

in reply to BeAware_ • • •Actually at least over here I also could create a positive list, restricting access to only predefined instances.
That said, the "asking for permission" is if some instance simply mirrors profiles "without asking for permission" each profile or instance it pretends to mirror or duplicate. This in any case is basically about good manners, not technical possibilities.
I didn't dig into some apparent nostr discussion itself but saw the possibility to register a profile for mirroring it. Well, actually the only way this could happen in a correct respectful manner is that a profile follows an account that than interpretates that following as a request or permission to be mirrored.
Not interested in supporting bluesky or disrespectful folks in any way so I guess this list comes kinda preemptive handy.
