How many "western countries" (whatever that means these days) actually have black lists? Because Canada and the US do not, as the Internet is all provided by non-gov't telco's. Chinatel is the only telco in China allowed to have international trunks, and Chinatel is 51% owned by the gov't. No one even knows how many international trunks Canada and the US even have, as they aren't regulated. At least mostly. In Canada, long distance phone carriers must register. But data over fibre is totally unregulated.
