Is it the simple website? If then how about to use Mudfish Browser Extension? If then, I think you can use PAC (Proxy Auto-Config) syntax to filter these domains.
For example, you can check [팁] 해외에서 한국 스트리밍 제한 우회하기 link though it’s written in Korean. For more syntax, you can check Example PAC File | FindProxyForURL link too.
