There might be a list for you on https://firebog.net/
We cannot. "Support" for this list should have never been added in the first place. These lists describe full paths. Assume they contain something like www.goodserver.com/user/cryptomining.js. The previous implementation would have blocked the entire www.goodserver.com as we - being on the DNS server level - cannot know the exact target you are envisaging. Only adblock plugins -- living deeply in your browser and can modify the content you see arbitrarily as they decide is appropriate -- can do such a deep modification.
The number of false-positives was rather high. Please don't ask for numbers, I'd have to assume some as I'm not looking forward digging through the many posts over the past years. I'll rather continue investing my time into preparing the v5.0 beta. I hope the community understands this.
I explained above while this list isn't the most thorough list available, at least not for DNS-level blocking.
Removing support for this list was the only right move we could make at this time. As @jfb said, a third-party should do and offer it to avoid multiplying the work that needs to be invested. I'm not aware of such a project right now.
