I used to be in that business, I'll tell you
Some of the Fortune 1000 crowd have their data flagged. If you have access to a service that provides such information, and you search for say "Bill Gates", there will be a shitstorm.
We were told by some 3rd party data sources that we were contractually obliged to maintain a list of "high profile" people, so those searches would always return empty. I pushed them for who "high profile" was. Bill Gates was obvious, because that was the reason the conversation came up. Theoretically, the list should include the Fortune 1000 crowd, and anyone who shows up in the news. They couldn't provide parameters, so that obligation wasn't possible to fulfill.
And on that specific search, they weren't searching for the obvious Bill Gates of Microsoft. It was someone with the same name in another state on an authorized background check.
The amount of data that I was exposed to was absolutely insane. Pretty much, I could tell you stuff about yourself that you may not even remember, plus your neighbors, relatives, romantic partners, and people you associate with. It was down to your hobbies, shopping habits, and even photos and messages from social media.
