Only if you relied on GOSSiP as your sole determiner of mail acceptance
or rejection.  That'd be foolhardy, as would relying on any single check
on incoming mail for such determination.  There is no one single
mechanism that can definitely say "accept this" or "reject this" for all
incoming mail, with zero false positives and zero false negatives.

Spam prevention, much like security, requires multiple layers (the
"onion" analogy) to be effective.  Anyone ignoring that does so at their
peril.
