Plus, I recently learned (via returned mail) that who knows how many thousands or millions of spam-mails have been sent "from" my domain name. I've long wondered why so many people look me up in "WhoIs." Now I know that these are angry folks wondering who's been spamming them. Apparently there's no way to stop this, since a spammer can put anything he wants in the "from" line.
This also happened to us at work. Very unpleasant. But those people WhoIs-ing you are just angry lefty philosophers, you know that.
