Hall of Shame of low-quality adblockers

You guys raise some good but not insurmountable points about AdNauseam, so I decided to make a pull request to it to test out and see how much it was being worked on. If it doesn’t get a reply from someone who works on that project within a week-ish, I’ll add that extension to the Hall of Shame.

Should their response be swift, however, I may in sharp contrast even add it as a software on FilterLists.com.

But why adding a legit fork even if it’s semi-abandoned?

What they do might be questionable, but this is not some shady clone, you can see who’s behind it.

My thought process at the time, was that I was a bit under pressure from Krystian and Kowith, so I decided to put their maintainers to the test. Would they be quick responders, or would they let pull requests linger for months at a time?

I was pleasantly surprised to see that they were quick responders (although they have yet to outright merge the pull request), and thus the latter scenario in that comment of mine came into play: That AdNauseam is now listed on FilterLists.com as a software tool.

Back to main topic, the Stylish isn’t an adblocker, it’s just an extension to customise website by using user stylesheet, also have userstyles.org for a collections of stylesheet published by users (kindly same like adding user script)

But yeah, it’s a fall of that after acquisition and found out it’s phone home every URLs that you’ve visited, include all of forms and queries too!

My addition of Stylish has a bit of a backstory to it.

During May of 2018, about a month before I learned that :style was a thing that existed, I made a bunch of single-site widener styles for Stylish, so at the time I treated it on almost the same scale as I’d treat uBlock Origin.

Then I learned about :style. And since userstyles.org had various problems already by then (Most notably its PayPal links were all broken), I created a uBO list that combined my Stylish userscripts (and a few userscripts made by others), and I’ve never looked back since, especially not after Stylish ran into such big privacy problems that it was suddenly auto-removed from my Chrome one day last summer.

Additionally I am aware that RU AdList has a Stylish version of its CSS entries, for those who for some reason would prefer a ABP+Stylish+Tampermonkey combination over simply using uBO/AdGuard.

uBO also need Tampermonkey + userscript for few Rusian/Ukrain sites e.g. sinoptik.ua or update scriplet spinnet abort-on-property-read regularly.

@ameshkov Are you familar with a project called AdLock (without a B)? I simultaneously see indications that it’s legitimate and non-legitimate, so I was wondering if you could find a way to look through its code somehow.

What I can figure out about it, is that it has a pretty similar business model to AdGuard, it uses AdGuard’s own lists by default (but the desktop version tries to hide it by encrypting the downloaded lists and claiming they’re based on EasyList), and it seems to be somewhat maintained.

At the same time, its settings aren’t particularly in-depth (Especially so in the desktop version), the desktop version installs an SSH certificate by default, and its code doesn’t seem to have any documentation on it that I can easily find.

This is a pretty obvious clone of AdGuard, which I guess is good news for us – we must be doing something right if people clone our products :slight_smile:

This is not the only part of AdGuard they’re using and trying to conceal. I can’t go into details at this point unless we decide what to do with them.

This is also similar: https://stopad.io/

But app is EOL.

Thanks for your interest in StopAd.

Unfortunately, this app is no longer available for sale or download.

Fortunately, our users with subscriptions will still be able to use the app as usual through the end of the subscription period.

We are grateful to you for your support.

Yeah, this is 100% clone indeed.

And here’s an interesting story on adblocker ultimate: https://www.ghacks.net/2019/07/25/mozilla-recommends-a-firefox-extensions-that-appears-to-be-a-copycat/

Effectively this seems like AdBlock anno 2016, and is not something I would give any major credit to FlashPeak for.

And also it appears that the edit button on this forum seems to have some kind of time limit for how many days/weeks it’ll show up under a comment. Which is a very bad thing in threads like these.

Or it could be related to how I had to log out and in again a few days ago. It’s difficult to tell for sure from my perspective.

Try this:


and all highlight “lang syntax” format gone.

That went pretty well, actually. :+1:

@ameshkov I truly applaud your work on exposing fake-AdBlock and uBlocker to the public, but I distinctly recall there was also an earlier lead that I’ve had surprisingly much problems proving after okiehsch from uBO doubted me on it, so I’m hoping you could help me look into it:

I firmly believe that AdBlock, Inc. (and not the actual GetAdblock team) were the guys who registered the uBlock trademark in Europe (https://euipo.europa.eu/eSearch/#details/trademarks/017822487), especially with https://adguard.com/en/blog/fake-ad-blockers-part-2.html establishing in the introduction that AdBlock, Inc. are/were indeed from Germany.

But since fake-AdBlock does not seem to have a website anymore nor any Wayback Machine archivings, I’m left stumped in trying to look up again my distinct memories that fake-AdBlock and uBlock.org had very similar GUIs, as well as any other things that could’ve connected those two extensions and sites.

Actually, @okiehsch is right, and the uBlock trademark belongs to the non-fake AdBlock.

The companies mentioned on the fake blockers pages do not exist in reality, it’s just Google does not verify developer accounts so you can write whatever you want there.


An extension called “广告净化器”, translated by Google Translate as “Ad Cleaner”, and which targeted PR-Chinese web browsers only, has apparently got in the PR-Chinese tech news by also having been engaged in affiliation theft, by somehow getting the ChinaList 2.0 list to add redirection entries that were only supported by that extension. At least that’s what I could figure out after I stumbled across https://github.com/collinbarrett/FilterLists/issues/1419.
