The main thing here is that you realise this is not only done to block ads but to react to anything some site owners do. The second thing is that the maintainer of this list is actually a kiwi, and works for a NZ ISP. Sad to see the thinking that any revenue is evil and should be denied, by lumping a community site like Geekzone in the same bucket as sites that overload ads, spam and other bad practices.

That doesn't supplement revenue. That requires work, which is time, which is a commodity that sometimes is not readily available.
