I'm surprised no one here is talking solutions. The fundamental problem is someone can connect to me and I have no way to trace it back to an organization who I can charge/sue. The first step is to start adopting standards that aren't free either in cost or in compute. For email, this could be as simple as requiring proof of work before accepting an email. For private telcos requiring the ability to charge the company connecting to my number would solve most of these problems too. I'd love spam if I had the equivalent of an 80's era 976 number.
