It costs a lot more internationally, so I'm not sure how much of a problem it really is. While many people would hate this, the same rule could be applied with "if you're forwarding international connections, you're responsible". Bad interconnects would probably drop immediately with a moderate amount of chaos, while legit foreign partners are found who can filter traffic on their end. |

I have a hunch that no telco wants to entirely block a foreign telco because they would lose money and because of the ensuing chaos.
Robocall friendly service providers intentionally mix robocalls with legitimate traffic to avoid terms of service enforcement. e.g. Robocalls are laundered by splitting across n carriers so spam (identified by bad ASR/ACD stats) stays below each carrier's threshold. https://news.ycombinator.com/item?id=12339739
