Your instance has data covered by GDPR, but the data it sends to other instances is covered by the same exceptions as the data you send in a email. Without exceptions for legimitate interests it would be illegal to send an email from, say, mailbox to Gmail or Yandex Mail.
I guess that could be in regards to user profiling.
Since no fedi platform aggregates user data like “user xy always upvotes topic a, therefore I will show him more on topic a via an algorithm”, or shows algorithmic advertisements, or sells user data for advertisements etc, I don’t think it’s relevant to GDPR at the moment.
Mastodon and Lemmy don’t actually share any data actually protected by GDPR, unless the users actively make it public (like using their real name).
Am I right in my understanding that if you run a federated Lemmy instance, you can see who has upvoted what, even on other instances?
Is that not something protected by GDPR?
No, things like your home address, your IP address, birth date, health conditions, religion, etc are PII.
Upvotes almost certainly falls into “legitimate purposes” since the data is required for moderation.
So, are you saying that Facebook holds basically no data covered by GDPR?
How’d you get that from that???
Well, ok, of that list they have my ip address, but nothing else.
They accept all of that information in one way or another.
