Here is a script to take the hosts from From http://pgl.yoyo.org/adservers/ and convert them to rules for Little Snitch.
Aug 25, 2019 Just grab the output and copy/paste into Little Snitch. The script is written to block access to any process, any port. You can also delete those lines and it will only block Mail. Or use the options to enter any process, port or protocol you want to block. LuLu is a great free, shared-source, macOS firewall that can block unknown outgoing connections, unless explicitly approved by the user. It runs on OSX 10.12+ and runs well on macOS Mojave. It can be configured to allow or block Apple signed binaries and has clear GUI based rule set that can be edited.
It has options to grab the entire list or grab new entries past a certain date.

Installation: Copy the text generated by the output from a plaintext editor into LittleSnitch Rules
Save the script in your home directory, I called mine getadblock.sh.
Make sure to make it executable:
chmod +x getadblock.sh
Output looks like:
File - GetAdblock.sh
Run Command
I have disabled all incoming rules, and explicitly added a block for ssh. However, little snitch blocks absolutely nothing.Rules:
