When you buy a domain name for your website you will probably be asked if you want to buy domain privacy for it. Domain name privacy is a service that hides your personal contact details from the public database WHOIS.
The public WHOIS database will display all your contact details if you do not purchase this; name, address, email and phone number.
Should You Buy Domain Privacy?
If you don’t get the privacy service you are likely to get endless spam sales calls and emails. There is also a security risk if you inadvertently upset one of your site visitors. Best to be on the safe side.
