There's almost no real privacy online in the US. When I search for my name my phone number and almost every address I've ever lived at it is publicly retrievable - on multiple sites. Even with a private WHOIS I get spam from various companies via my registrar asking to speak to me about making a website.

You can get some of the major sources to remove you with a service like Optery [0]. Costs a few bucks, but if you let them work at it a few months you can drop the subscription and the effects will linger for a while before you start finding yourself on public databases again.

I used it myself and I have trouble finding information about myself, even with my inside knowledge. If someone is determined enough you probably can't really hide from them, especially if they have any connections to law enforcement or one of the big data sinks. But you can definitely make it harder for casuals.

It's worth sitting down for an hour and filing a bunch of information redaction requests.
