You can ad your own adlists by editing /etc/pihole/adlists.list. There are a lot of curated lists with domains circulating the internet for example https://v.firebog.net/hosts/ https://v.firebog.net/hosts/. I found that with the default lists it runs very smoothly but if you start adding a lot of domains it might break some sites. If you break a site you can always whitelist it or disable blocking for a while through the web interface.
