Your site isn't "banned" in any sense: you are leasing your domain, and as part of the lease agreement, you are required to provide accurate contact detail. That was the case even before ICANN brought in the 2013 RAA.
As wtallis wrote, this only applies when you initially register a domain or modify the contact details associated with a domain. While registrars are required to re-validate contact details, they only need to email you to notify you that you should check that your contact details are still accurate, which they currently have to do already. Of course, if the email bounces... but if that's the case then you've seriously screwed up.
