Federated services have always had privacy issues but I expected Lemmy would have the fewest, but it’s visibly worse for privacy than even Reddit.

  • Deleted comments remain on the server but hidden to non-admins, the username remains visible
  • Deleted account usernames remain visible too
  • Anything remains visible on federated servers!
  • When you delete your account, media does not get deleted on any server
  • EU instances transmitting data there might.

    This is an interesting thought, as data transfer between the US and EU has been an issue with other social networks. Federation between an EU instance and a US instance could be seen as the same thing - data for EU users is being transferred to non-EU servers.

    • It’s very possible that an EU instance that comes under regulatory scrutiny for whatever reason will have to start requiring Data Processing Agreements (DPAs) from every instance it federates with.

      Ultimately that would likely result in a few paid, professionally run instances, which only federate with each other and maybe a few similar instances in other regions with the capacity to provide DPAs.

      And next to that, a forest of independent, non-conforming instances flying under the regulatory radar; an entirely separate fediverse from the centralized one where instances disappearing is a regular occurence.
