ItPro.co.uk did a piece on a rule change for .UK registrants where if the domain is used in anyway for business, which could include parked page or blog with adsense, that their info will be published.

From the article:

Nominet, the company which manages the registry of .uk domains, has issued a rule change meaning that domain name owners’ home addresses will be published in online search results. Those signing up for the registry must now also agree to display their full names on the company’s public database.

Previously Nominet allowed registrars to opt out of having their postal address being shown in search results. That has now changed, according to a post on the firm’s website, so that only domain holders who are “non-trading individuals” can opt out.

It goes on to define that any website that uses pay-to-click advertising or trades in any form over the internet will be counted as a business and have its details revealed.

“To opt out, you must be a ‘consumer’” a Nominet employee told blogger Andrew Norton. “[An] individual who has registered and is using the domain name for a purpose unconnected with any business, trade or profession.”

A survey by EMC revealed that 59 per cent of people in the UK believe that their privacy is fading away, while 84 per cent expect it to be gone completely within the next five years. People want the benefits of technology without the sacrificing their own privacy, the survey’s conclusion read.
