Reporting spam should be the other way around, it defaults to assuming a normal interaction. Consider: if you get harassed with a call or text you don't like, you send an SMS with that phone number to some known short code. You then receive $1 from the caller. If the caller cannot be found, the last verifiable link in the chain is responsible for paying the fine. This would cause carriers to behave overnight, instead of allowing foreign call centers to spoof other people's real private numbers with your area code.
