That also seems to be a risk with most centralized social networks these days as well.

Our LinkedIn profiles have been scanned by scrapers, Instagram photos used for facial recognition training, Twitter / FB posts replicated in a bunch of downstream places, archives, and search indexes. Not to mention data being sold to third parties.

At this point, I assume if I post it publicly online, it is no longer in my control where it ends up downstream and I assume it will be online somewhere forever.
