I think the long term solution could be in making the network providers and ISPs more responsible for the malicious traffic originating from their networks. For example the botnet traffic is best stopped at the origin. If there was some pressure for the service providers, I'm fairly sure they could do more to detect subscriptions with compromised devices and take appropriate actions. Actions can include educating the users and if necessary, blocking the subscription until problems are fixed. While this certainly would not immediately cover the whole world, it would be a start. On the website level you could then treat traffic from networks that have agreed to cut malicious traffic in different way.
