Rather than try to legislate compliance (how many spammers are going to
abide by our terms?), simply don't collect e-mail addresses at all. If
we want to notify someone of an improperly formatted entry, build an
error response into the protocol and give the user notification that way.
If we have a need for tracking entries, make it voluntary and allow the
user to choose a handle and password via a web form (or build that
into the protocol as well).
