Note that his file http://someonewhocares.org/hosts/ does not contain
ALL ad sites. This file he maintains is updated very frequently by him
from reports of new ad sites from people like you and me but it's hard
to keep up with them as new sites are springing up all the time. You

Thanks, I actually have that very file and it works for sites like
Google search results sponsored ads, producing a "Unable to connect"
if clicked on. However, it doesn't block all of them which is the
reason I use ABP, as well. For TLD sites that I frequent often and are
not irritatingly spamming, I whitelist them in ABP.

KISS. My simple solution to the ad problem is to use the hosts
file. Most of the sites you are browsing do not have the ads
embedded in them They use links to the ads. Placing the address of
the ad links into the hosts file redirect them to an internal to your
system (or wherever you would like) that does nothing, but allows the
original site to think the ad has been placed on your screen. For a
ready made hosts file and explanation of how it works see:
This means advertisers and publishers can simply change the code
they use to deliver their ads to defeat them. This type of
ad-blocking is often easily detected by anti ad blockers, which are
deployed on the sites of more than 50 popular publishers. Finally,
traditional ad blockers fail to block native ads that look like
normal content, which is why your ad blockers won't detect and block
sponsored posts on Facebook.
Perceptual ad-blocking, on the other hand, ignores those codes and
those lists. Instead, it uses optical character recognition, design
techniques, and container searches (the boxes that ads are commonly
put in on a page) to detect words like "sponsored" or "close ad"
that are required to appear on every ad, which is what allows it to
detect and block Facebook ads.
Seems to me that these new detection techniques, once incorporated,
could be countered by ad agencies by disconnecting the "sponsored"
or "close ad" display DIVs from the actual ads themselves and it's
not clear how they will be able to stop sites that don't display
rendered hints as to forthcoming ad content.
