> if a spam operator has 33% legit traffic, do you kill the spam operator and the good traffic with it, or what? Yes, we should with these long-time, serial offenders. Having legit traffic is just a fig leaf cover for them anyway. Any legit reseller clueless or negligent enough to accidentally stumble into business with these guys will switch providers as soon as their customer's calls stop connecting. Also, no real telecom providers are routing meaningful amounts of traffic through these shady operations. Any legit traffic on their networks is mostly coming from fly-by-night, bottom-feeding telecom resellers in the same countries the spam calls originate from. Any retail customers of those resellers are probably paying ripoff prices for unreliable per-day or per-call service anyway. It's not people with normal pre-paid monthly service from any legit telco you've ever heard of.
