No it would not. That is what AWS wants you to to.

And such lawsuits can go both ways. As soon as a company moves
beyond protective blocking of port 25, to punitive blocking of
all traffic from AWS, they run the risk of being the target of
a damages lawsuit. Not to mention complaints from their own
customers.

There simply is no simple solution to this problem.
