if an author could be held accountable for lying.

authors would make assertions for either of two reasons:
1. they increase the liklihood that their messages would reach the
intended audience because recipients have explicitly allowed it to
bypass their spam filters.
(because those recipients specifically said they want particular kinds of
advertising. there are people who need to receive narrowly-focused
advertising or find it useful)
2. there were a penalty of some kind for not making assertions in some
circumstances (e.g. US laws requiring some kinds of messages to be
labeled as spam or sexually-explicit)
