Domain Privacy
Currently, you contact details such as phone number, fax number, address and email will be displayed whenever somebody perform WHOIS on your domain unless of course if you have bought the domain privacy service. It is a bloody requirement that ICANN request from whoever purchasing the domains (except for the .CA domains).
I am totally clueless why in the world ICANN post every details of the domain owner on the WHOIS record. I do not mind my email address from appearing there but clearly not my every other details such as addresses and phone number. So the only solution, buy a domain privacy service at around $10 to prevent my details from appearing. It should be a FREE service available to all the domain owners with option to switch on/off the listing of details.
Although lots of people talk about online privacy now a day (especially on Google and all the various social network), not many has voiced out about the domain privacy.
