I reckon that arms-race only exists because the web is fundamentally broken due to having/allowing some level of anonymity. If you could perma-ban a spammer's real world identity or that of his company (or any company they're a part of), then there would be no need for the arms race. Just a continual "negotiation" whereby bad behavior is informed and requested to stop. And if that entity decided to ignore such a request they'd get the nuclear option of being permanently banned from the platform. You could argue that such a system would not be that different to real-world licensing requirements/restrictions as applied to lawyers and doctors. Just follow the identity like you would the money, and you could solve a good chunk of this issue.
