ZoomInfo (public company) for example provides a free plugin for sales people which is scanning email for all the email signatures and then they sell all that data to their customers. Even crazier is they take data from their customer’s CRM systems.
DiscoverOrg is buying data from third parties without really knowing how they got the data.
There are a bunch of apps and browser plugins that read your emails or contacts and then those companies sell that data to third parties like these data brokers. I use very few browser plugins because of this threat.
If you have somehow acquired a list of contacts you can get a lot of these companies to purchase it with very few questions.
I used to operate a dozen or so small web sites. A spammer once offered me a crazy amount of money for the mailing lists. When I declined, he offered an even crazier amount of money to buy all the web sites, in their entirety, including mailing lists and social media accounts.
I ended up selling him the one web site that didn't have a mailing list and only rudimentary social media presences. I bought a new car and moved to a better city with the money.
