Eh, if i wanted to i could scrape various instances and do whatever i want. The question is would i be able to pin information to identities without the accompanying meta data or would i only get a big text corpus.

The benefit of the fediverse is that no instance can sell the whole package, because most instances only have the posts of most users and nothing more. Reddit has way more additional data that can be used to track and identify someone.

No, the right to be forgotten is about data that can be used to identify you stored by a service provider. It’s not a right to have every record on the internet purged.

I guess you could force Instances one by one to forget you, but a single provider only has to make sure they deleted the data they stored.
