Yeah. For various article-context reasons I am concentrating on the blocking of "ads" here rather than on "malicious code". The latter is a much more complex problem to solve in the first place, though: like, it relies on a specific model of opponent that is also extremely dumb; amazingly, this opponent exists in the wild, but I swear it is only because people who go out of their way to block them with simple techniques are so rare as to not be worth investing into including in your un-targeted resource utilization attack. (And FWIW, the ad pages I run into that are maximally bad -- ones that abuse the browser using history state tricks, popping up notification boxes and printer dialogs, sometimes even managing to lock up the entire rendering engine on purpose in an attempt to get the user to agree to the terms of the scam -- all have URLs that are constantly being randomized so often that I have a hard time showing them to other people.)
