Precisely. There is nothing that can be done about doxxing if the information posted was already available to the public (The white pages).
As has been said on this website, the best thing you can do to stop yourself from being doxxed is to keep a low profile on the net. Use VPNs, don't use recurring usernames/aliases or even similar ones, use separate emails for business and pleasure (For the pleasure email, make sure it's one that doesnt give away your identity in the address or name associated with the email). I think the big one would be staying off of social media, delete that shit, it's hot garbage anyway.
Common sense on the internet is the best defense against doxxing, so it's best to use it.
