FYI there is also the California and Vermont data broker registries where you’ll find about 500 registered brokers to go through. “Wow that sounds like an impossible task!” And, yep! It is! There’s been some proposals for bills that would give you the ability to delete your information from many registered brokers at once - in years past Ossof pushed a DELETE Act, eg. Right now in California there’s SB 362 working towards the Assembly that would do the same. So if you live in CA you should definitely check out the bill and contact your assemblymembers to support. Because going broker by broker is an impossible challenge.
