@nartagnan @stux @latsss if your user account blocks the threads domain, no one there can follow you and so your private/followers only posts will not be shared to Meta’s instance
Regardless of your block strategy, Public posts are always accessible to anyone in the web for any purpose they please (including Meta).
Unlisted posts can also be scraped out from the APub network, regardless of block strategy, which an industrial player like Meta would do.
