heh I made the mistake of engaging with that once. oh boy.... They could not wrap their head around the idea that the hosts method is limited in some use cases. This could not be blocked without blocking the main host too. https://example.com/adverts-folder/advert.jpg https://example.com/adverts-folder/advert.jpg Now it sort of works in practice as most of the advert networks do not host on the same domain. It is good at catching out whole bad domains but partial ones it is not very good at. Which some domains will do using a reverse proxy. Also at one point a hosts file was linear scan. No sort of hashing or binary search lookup. Not sure if that was ever fixed in windows or linux. So a small number of hosts it was ok. But as the file grows it starts to add up.
