在「Amalgamated hosts file」這邊看到超大包的 hosts，拿來擋廣告：
This repo consolidates several reputable
hostsfiles and merges them into a single amalgamated hosts file with duplicates removed.Currently this amalgamated hosts file contains 27,148 unique entries.
一包 hosts 有兩萬七千筆資料會不會太多了點...
bind可以，印象中9.8以上有支援RPZ(Responsive police zone)，直接塞進去就好了

手動轉了一個 unbound conf，正在看效果。
