I test my BlockLists locally before pushing to github usually with a yacy search engine.
Something happened and Google was Blocked.
I checked my source with github and it was null for update and changes.
I do post out of context. I take lots of lists and parse them and have a prewhitelist program that I wrote in QB64. The trouble is I don't have anyone else to tests the lists locally before pushing them to github for anyone to use I rely on the public who use them for feedback.
Yacy, I used the other day on shared room rental sites. Could be a forum that you are interested in.
Its probably best if you try it yourself https://yacy.net/en/index.html
I do use it to test my blocklists, also I tried crawling some of the mining sites to see whats there.
