We recommend WHOIS Privacy to all non-transacting websites where it is unnecessary for your personal details to be visible and accessible. For example, If you are a blogger hiding your details will help prevent unsolicited contact and other unwelcomed attention.
If you are an online shop, business or agency we recommend leaving your personal details visible. Having your contact details easily accessible on the WHOIS database will help reassure your customers that you are a trustworthy outlet who can be easily contacted.
