I opened I support ticket with these robbers about an hour ago having received one of their emails about this for two domains I have never had domain privacy on and have no requirements for.
I go into my control panel, change the domain privacy settings to NO for both domains, click Save and it changes them back to YES again. Not only did I never want it in the first place, but it cannot be disabled. The domains aren't up for renewal till 2019 and 2020 so guessing they're just hoping users will ignore this and they'll add their stealth charge when the time comes.
