1) ban TV-proxy-as-a-service - straight up go to every representative there is and start pushing and lobbying and everything to stop spammers from distributing over non-computer devices, especially legally
2) make old commits more expensive to access than new ones. Legit users are not going to access those much, so they can pay the time. I assume diverse (unpredictable?) difficulty can also make spam pulling harder
I would think that residential proxying would be illegal already, as it is a network intrusion. The trick is chasing down the offenders, proving their actions did harm, and getting them to pay. None of those steps are easy, even if there are laws to assist. Otherwise, spam would be a solved problem.
