If you are looking for more blocklists, I maintain several. I recommend my 'Ads & Tracking' list for most people. I also have an aggressive list - which I don't normally recommend. I also have a Google AMP list and a Facebook products list (not just facebook - but their other products as well). Anyways, you are welcome to check it out and give me any feedback you have:

Easylist was meant to be an adblock browser extension list and as such it's not perfectly suitable for a DNS blocking solution [0].

> select filter lists for use in your browser provided that you are using a compatible ad blocker (tested with Adblock Plus, AdBlock and uBlock Origin).

The replacement is any other list of hosts available for PiHole.

They have other blocklists. In fact, easylist isn't even enabled by default in Pi-hole. I've been running Pi-hole with its default set of blockers and it still blocks quite a bit, but there are all sorts of lists you can add on top of that.
