If I intentionally design (and program) a social network that uses a technology (blockchain,...) which does not allow for alteration / erasing of user data, what happens in case of a right-to-be-forgotten request? Were there already any cases like this?
What happens for other cases where the technical design disallows compliance with government request (for example, using end-to-end encryption for all communication, meaning I can't give goverment agencies like FBI access to private data on request)?
