Do they get some kind of real-time feed that tells them “hey this URL popped up in the web today, but it is a tracker, so block it”, or is this exercise is mostly helped by the crowd ?

    Regular expression magic.

    A lot of ad networks have a pattern to the name or the window the advert appears in.

    Using regular expression you can find just the adwindow and ignore the actual content.

    Now what is regular expression? A wizard language.
    ask any programmer about RE after 4 beers and watch the hate wash over their face.

    I thought they could just tell by the code if they had a pop up or not and they just have to stay updated on how they keep changing the way they’re presented. I could be wrong though.

      Maybe a general pop-up blocker which is built into modern browsers now, but something that blocks tracking and ads (for example uBlock Origin, AdGuard Home, PiHole…) works off of a list which is kept up to date by crowdsourcing. I’ve never contributed to one of these efforts, but there are lots of people dedicated to the cause.

        So there’s like a Wikipedia crew of ad blocker contributors? I had no idea, that’s pretty cool. Thank you adblock crew.

      The problem with this approach is that the companies will just change the way ads are shown. DNS blocking is impossible to stop, provides you block every ad website.

        DNS blocking is easy to stop, you just host the ads on the same domain instead of putting them on a subdomain. There are plenty of ways to do this already. Only reason it works right now is that lots of them have their own separate ad domain that they host from.

          I hate Amazon for this, and won’t use their apps or pages if I can avoid it (including the amazingly brief foray into the Amazon App Store years ago which only served ads from Amazon domains)

          Because so much of the world runs off Amazon I really can’t block that domain effectively without breaking large portions of the internet. Tho now that I’m not using Amazon actively for anything, the broken-ness might be fine. Guess we’ll find out!

    As someone who runs a popular blocklist collection, I’ve come to find that most of the MASSIVE lists are people who collate a whole bunch of lists together and then promote their “one size fits all” solution alongside their donation link. There are very few original high quality ad-blocking lists maintained (where originality is defined as a sizeable amount of unique entries not shared by other lists) and almost all don’t appear to openly discuss the magic sauce behind their lists, outside of the obvious case of user submissions.

    The easy way would be to make a website sign up for all the ads and see what happens. Subtract your website from the data and there’s the ads.
