> You're telling me that to remove my info I have to essentially give (through your service) all these companies & data brokers my info so they can opt me out, and actually trust them that they'll do so?
Other people raised that concern when this appeared on HN (https://news.ycombinator.com/context?id=27668140), and at the time, that’s indeed what the service did.
Even if one ignores intentional misuse, simple incompetence by a data broker seems like enough to cause a problem. It only takes one data broker to commingle fields from opt-out requests with existing data (and then share/sell/trade that existing data) for the opt-out fields to spread.
