  If they're using the same methods to spam, they're identical so far
as the recipient can tell.  If they're using different methods, then
they are technically different, and technical methods of
distinguishing them can deal differently with each kind of spammer.

  And if we don't know what the flaws in SMTP are, we don't even know
what kinds of questions to ask, to see which behaviours are more
significant than others.
