or they pretend to be authorised. and that is precisely why stakeholdijg isn't both ineffective and dangerous. people pretend to take and keep custody of an individuals identity and use it as they wish without permission - permission less mining - and parade it as open source and fair game. when in reality, they breach personal identity boundaries and they use actual violence/blackmail to subvert individuals from being vocal about their situations.

You raise a valid concern about personal data in regard to the adherence of explicit regulatable transparency and dealing with security bypassing credential-related trusting factors dominating ethnocentric models which network systems structure analytical features around integrity dependent facts optimized from incorporating such enlightenment where at all possible.

there's no way to stop the stakeholder system now short of the entire blockchain collapsing and even then ghosts data will remain like free radicals. personal ai bots with exclusive keys are an excellent answer. and a smart phone as it's own entire encrypted key system with an ai and mining and storage system is the best way to do that... but that's another conversation.
