Since no (real) validation is performed, and the address does not (even
in theory) identify the authoriser of the change, I don't think *anyone*
can determine *anything* from it!

N, you missed at least 6 "NO"s.

This would be a huge step backwards. PLEASE DO NOT EVEN CONSIDER THIS!

Yes, just a particularly bad one. Email, however, is still better than
clicky, clicky, click through a GUI.
Forcing operators through a web interface will significantly worsen the
data quality of the whois.

That is exactly what I was suggesting, yes.

Perhaps easier to use the mnter name rather than trying to grep an email
address associated with that mntner? Then no extra attributes with email
addresses in it to send spam to.

I think the solutions implemented at RIPE and APNIC fail to recognise
that attribution is important.
