Is it possible to add or remove WHOIS privacy to an already registered domain?
As of now, there is no possibility to add or remove WHOIS privacy to an already registered domain.
We have the following feature requests scheduled for one of future OBAS versions -- PBAS-19931 "Ability to enable/disable whois privacy for already registered domains" and PBAS-23316 "WHOIS privacy should be domain resource".
If there is some domain without WHOIS privacy and you need to add it to the domain subscription the only way for now is to terminate the corresponding domain subscription without actual service termination (domain will become marked as "Registered Elsewhere" after that) and then create a new subscription for it with WHOIS privacy enabled. This procedure could not be performed from end-user control panel -- only the Provider or a corresponding Reseller may do it from PCC or RCC correspondingly
