"Starting 9:00 AM EST on 2/4/2014 all of your domains will be protected via our WebLock Program"
They are only saying you will be protected via their WebLock Program, not enrolled in their service. But they are deliberately ambiguous to make it sound like they are the same thing.
"To establish Certified Users and pre-register authorized phone numbers and email addresses please call 1-888-642-0265 "
"If you wish to opt out of this program you may do so by calling us at 1-888-642-0265"
"Give the security team a call and they can explain 1-888-642-0265"
They are pushing hard for you to call them, that is where they will attempt to get you signed up for this "service"
