Data Broker Opt-Out List
If anyone cares, there are a nontrivial amount of companies who have your 'private' LinkedIn info.  I don't know if they make fake accounts to friend you, recruiter profiles, or buy it from LinkedIn.  I asked one to please remove my info, and they sent me a CCPA form.  I told them I didn't live in California, and an agent acted confused and told me to just fill it out, it's the only way to remove it.  In short, don't trust LinkedIn.
