Or the advice (full disclosure: co-author ) in SSAC SAC44 ( http://www.icann.org/en/committees/security/sac044.pdf ) and SAC 40 ( http://www.icann.org/en/groups/ssac/documents/sac-040-en.pdf ) which recommend (amongst other things):

"Registrants should consider the benefits of using mail domains for contact emails that are managed separately from the domains that can be accessed from an individual domain registration account so that an attacker cannot interfere with a registrar's ability to contact the registrant. Registrants should also consider other measures to mitigate this threat. For example, a registrant could distribute its domain name registrations across multiple domain name registration accounts (and possibly across different registrars). Example Networks, Inc. could manage example.com using account “examplenetworks1” and example.net using account “examplenetworks2”. Email addresses for points of contact for example.com could then be assigned from a mail domain operated under example.net. Similarly, email addresses for points of contact for example.net could be assigned from a mail domain operated under example.com."

It is, er, [ sad | hilarious ] when your domain malfunctions and no-one can contact you to let you know that this has happened because the contact is within the busticated domain…
