But this is really a chicken-egg situation. How do you tell companies to delete your information without telling them what identifies your information? It's in these companies' interest to make this as difficult as possible, so a solution based on data hashes is highly unlikely to appear out of their good will alone. This requires strict regulation and high fines.
There's also the issue of proving ownership of the data requested for deletion. Even in the EU with the GDPR, which is arguably the most progressive data privacy regulation we have, companies routinely violate this by requesting even more personal information from the requester.
I've wondered about this too.
I have a common enough name that about 2/3 of the info data brokers have on me is garbage.
If every data broker could be relied on to faithfully delete my info I would sign up for Optery or Incogni today. I don't, because if even one of those 2/3 is a bad actor I'm just expending effort to clean up their data.
Specifically, the data I don't want them to have.
On past projects we've recorded the time the user submitted a from (with a checked consent checkbox), but this doens't feel like rigorous proof.
Even test cases will run into data sharing issues.
amazingly enough the law is more clever than programmers assume it is, and the clever dodges programmers come up with tend to be seen through and just lead to jail time.

However, I would ban surveys because they can lead people to vote for the wrong person due to social pressure.
Given that these companies, like Incogni and DeleteMe, are now sponsoring big time YouTubers I'd imagine they are soon going to get a much closer look. At minimum, they are making far more people aware of the situation and data out there. Even though many of the VPNs fall far short of the promises, it is setting a strong signal that people care about privacy and entering the public lexicon is the first step. I hope these can be a catalyst towards more state or federal privacy protection.
