My Own Lists?

First thought - blocking YouTube ads with these domains will prove fruitless, and may interfere with your desired content. Very long running thread here:

Second thought - in a hosts formatted file, the IP comes first, then the domain name. You have this backwards.

Pi-hole will import lists that are either in hosts format or simply a list of domains. If the list is in hosts format, Pi-hole will strip the leading IP's and keep only the domains.

All three of these line entries below can be parsed by Pi-hole, and only the domain name (www.jiztini.com) will remain:

0.0.0.0 www.jiztini.com

127.0.0.1 www.jiztini.com

www.jiztini.com

Are you intending to block this domain? Why do you have the actual IP listed along with the domain?
