Why go through all that mess? You call up their new upstream, say
you're a representative of XYZ, and customer ABC does not have
permission to announce your netblocks. I know InterNAP requires
that they get consent from the netblock contact, I don't know about
other companies.
And so it doesn't happen as a prank, while on phone with them, tell
the person to send an e-mail to the netblock contact, you open up the
e-mail and read it back to them for verification, it seriously can't
be that complicated. kthkxbye.
