You sure about that? EasyList, the most common block list, clearly intends to block ALL ads, even self hosted ones. it blocks by css class name, directory name, image dimension, etc. It's updated frequently as users report unblocked ads.
(Not to mention how incredibly hard it would be to sell ads set up like that.)
Doesn't that flag a lot of false positives (in fact, I have personal experience of an ad blocker that did exactly that by blocking images with numbers in the filename)? Conversely, there's no way that can block ALL ads, unless it literally blocks all ... content.
Yes, certainly. But it's still the most popular filter subscription. I think this suggests that most people using AdBlock want to block all ads, not just network ads.
