Bout ten years ago I pissed off some GNAA idiot trolls on twitter, so they did a whois on my domain. I never updated it from my mom’s address so over the course of a week my mom got three cases of qurans and several large pizza orders (10+ pizzas each time), all of which she declined to accept.
Lucky she didn’t get swatted, though this was before they became such a big thing.
You bet your ass all my domains now have privacy settings enabled.
