> You're telling me that to remove my info I have to essentially give (through your service) all these companies & data brokers my info How can you index into a hashmap, an array, or a DB table without a key? Answer: you cannot. There's no way for data-broker opt-outs to work without uniquely identifying the individual who wishes to be removed. Sure, I agree that "GDPR-like regulation and actually enforcing it" is the proper solution - but how long will that take? Five years? Ten? What if I want my personal data removed from these brokers now? Edit: now that I think about it - you could build some scheme where you give the data-brokers a cryptographic hash of some personally-identifying information, so if they don't already have you in their database, then they can't get your information. But, in order to do that, you'd need regulation equivalent to the GDPR (otherwise they'd never do it), in which case the above argument still applied.
