Define maximum for us?

I use Namecheap and like their services. They have domain privacy aka it’s registered with their information instead of yours. If you just want to hide your name from people Googling or using a domain whois lookup, that’ll do the trick. If you’re trying to hide from people, you might need something more specific.

If it was never intended to be public, you might screw other living people over in the process. Think: revenge porn.
