We have a [blacklist](https://discourse.pi-hole.net/t/commonly-blacklisted-domains/305), which you can use for [ads that are not blocked by default](https://discourse.pi-hole.net/t/how-do-i-determine-what-domain-an-ad-is-coming-from/1522). You can also [supplement the default lists from other sources](https://github.com/pi-hole/pi-hole/wiki/Customising-Sources-for-Ad-Lists).
