This is just a collection of random ublock origin filters that I use above and beyond the filters available within the addon itself.
IANAL but since its pretty much just a list of third party servers/urls to block content from and was found on public forums like reddit, I am 99.9999% sure there is nothing copyrightable about this and it would fall under public domain/fair use.
However, I do believe in giving credit where it's due and try to link to the source where I found them whenever possible.
The links to the pages are included as comments in the file itself.
