I own a couple of domains where I currently have "WHOIS privacy", so my contact info is not revealed in the WHOIS database. I've learned that this arrangement has a significant pitfall, that is, it's the privacy company that really owns the domain, and they license it to me. That seems bad.

I'm not a business, so the only address I can currently list is my home address, which I'm uncomfortable doing.

Therefore, I was thinking about renting a small P.O. box and using that as the address of record. Are there any significant drawbacks of this approach?

One possibility is that people might actually send me snail mail that I need to see, meaning that I might need to actually check the P.O. box instead of ignoring it. Does this happen? (I haven't had any forwarded to me in ~10 years of owning a domain, but that could mean I just haven't caught the attention of folks who would do it.)

Are there other risks or drawbacks?
