from what I see there are 2 solutions:

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

> straight up go to every representative there is

In every country of the world? I think you might have a significantly easier time convincing Samsung and LG to ban this via their T&C.

3) just track down the people and arrest them. DDoS is already a felony, and residential proxies aren't untraceable to law enforcement.

If there was a way of detecting the proxy SDKs, it would be a simple matter of banning the device. Or at least naming and shaming the apps that use them.

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.
