I suppose each registry has their own policy for whois data. Although I believe that CIRA states that only real people are valid as contacts (i.e. roles such as Domain Admin are not allowed), we all know CIRA is not proactive in ensuring rules are followed. However, a complainant could request CIRA to follow up on it, at which time CIRA would probably only ask the user to correct it. If they refused to, then CIRA would have to decide if they're actually going to do anything about it, and if so, what. In response to such a request, most registrants would probably just turn on privacy and thus eliminate the problem and the complainant basically has no satisfaction or recourse. Thus its a pointless exercise... And a meaningless rule. Our registrar contacts here such as
@FM and
@bmetal would probably have the best insight into this.
