Hm. I remember once looking up a spammer's domain and finding a completely nonexistent address. I knew it didn't exist, because it was ostensibly in my own small town :) Maybe they thought the place is so remote, nobody would ever check. But if you're going to put down an imaginary address, why not put it in a big older city? Even the cab drivers couldn't swear under oath that there is no such place as Dunkelgasse No. 17.
Does ICANN have any bright ideas on how the registrars are supposed to know their information is accurate? Are we all about to get phone calls from people with dense Asian accents verifying that we exist?
