In a free society should sending spam (marketing) emails be considered a crime?
It seems to me unless a person is hurt by spam it cannot be considered a crime. The only possibility I can see is if someone owns the email exchange servers on which the emails must be stored. In that case I can see an argument for it. However, it is usually not individuals that are hurt by spam but rather, for example, companies like Google who own massive abounts of email storage space.
If this is true, then could each of us sue junk mailers for the same reason since we must pay for its disposal?
