If you have privacy protection enabled on a domain name under what circumstances would the domain registar reveal the registrant information to a 3rd party or authorities?

Law enforcement subpoenas, court orders and other legal processes received, violation of the domain registrar's TOS, compliance  with ICANN rules and UDRP/trademark disputes, registrar believes you are violating the law or engaged in spamming, non-payment/cancellation of the privacy service are the most common reasons .

Here is Tucows:

GoDaddy's Domains by Proxy has a similar (but longer) list of things that will cause them to reveal your identity: (see #4 https://www.godaddy.com/agreements/showdoc.aspx?pageid=DOMAIN_NAMEPROXY )

If you do anything against their ToS.

If you host a website defaming the country, hatred websites, etc. the countrymen might come to get you and they need information from the registrar >.<
