Anti adblock warning is displayed on https://www.meta-chart.com. They are using Admiral's (https://getadmiral.com) anti adblock technology.

Error URL: https://www.meta-chart.com

Arrived at this domain from https://github.com/easylist/easylist/commit/a4d380ad1a3b33a0fab679a1a8c5a791321622b3#commitcomment-23587399

@ryanbr There removed an Admiral ad domain from EasyList citing a DMCA request which has not been posted publicly till now. The filter that has been removed is:
||functionalclam.com^$third-party

This ad domain is being used on this website (meta-chart.com) among others to display the anti adblock warning.

_Note: Using uBO 1.13.8 with the default filters and settings._

I created a new generic scriptlet to make it easier to abort according to current inline script rather than arguments passed to specific function calls.

For example, in the current case, this works without the need for setTimeout-defuser.js:

meta-chart.com##script:inject(abort-current-inline-script.js, Promise)

Promise is the entry point, inside which the scriptlet will look at the current inline script to find out if it matches the 3rd argument. No 3rd argument means always matches. In plain English words, the filter above means: "If window.Promise is accessed directly from within any inline script, then abort execution of that inline script". A 3rd argument would be used to further narrow by requiring a match with the text content of the current inline script.

Copyright law does not protect domain names, so how can this result in a valid DMCA request?
Anyway
meta-chart.com##script:inject(setTimeout-defuser.js, "ubo", 300) meta-chart.com##script:inject(setTimeout-defuser.js, [native code], 15000)
fixes your issue.

DMCA has nothing to do with filters and filterlists and can't be used to compel someone to remove a filter from filterlist. This is laughable and bogus use of DMCA at best.

Solution does not seem to work for Nightly + uBO 1.13.9b8. I wonder whether this is a Nightly bug causing scriptlets to not be injected, but I can defuse properly with bab-defuser.js on blockadblock.com.

gorhill picture gorhill on 11 Aug 2017

I got it to work with meta-chart.com##script:inject(setTimeout-defuser.js, setTimeout).

Anybody else can reproduce the issue with Nightly?

If I understood this right, what DMCA does is forcing websites like Easylist to delete some others so they can have ads. So, when we use adblocks like ublock origin, it doesn't download "website X" from Easylist, therefore, it allows this ad. Am I right? then, why not allowing the user to export our current list of websites and just add more with the time so "website X" is in our filters and can be blocked?

The DMCA-complaint states that:
The code in question attempts to circumvent copyright access controls to copyrighted content on the site listed in the title of this commit.

So in essence Admiral is arguing that ||functionalclam.com^$third-party violates the right of the website
mathwarehouse.com, to only allow access to their copyrighted content if you also connect to functionalclam.com.

I do not know what you mean by

why not allowing the user to export our current list of websites and just add more with the time so "website X" is in our filters and can be blocked?

you can already import any list you like to your uBO setup and add any website to your own filter list.

okiehsch picture okiehsch on 12 Aug 2017

@SMed79 @okiehsch @gorhill I think this might be the right place to ask. So, what came out of the DMCA controversy? I haven't been able to follow it after the initial day.

gotitbro picture gotitbro on 20 Aug 2017

@gotitbro Easylist caved in and removed the filter which was what Admiral wanted after all, however this action caused Streisand_effect on a widespread on Github and in other places and functionalclam.com was blocked on multiple repositories, on top of that, BarbBlock, an extension built to fight DMCA came into existence.

it seems meta-chart.com##script:inject(abort-current-inline-script.js, Promise) does not work anymore

mapx- picture mapx- on 29 Sep 2017

The filter still works for me on that site. If I un-check "uBlock filters", I get the anti-blocker warning. If I enable "uBlock filters", no warning.

gorhill picture gorhill on 29 Sep 2017

I tested chrome 61, 62 + uBo 1.14.8 + default filters (included updated ublock filters), firefox 57 (uBo 1.14.11rc8). I get always the warning msg.

mapx- picture mapx- on 29 Sep 2017

With Chrome 61, Firefox 56 and uBO 1.14.8, or 1.14.11rc8, all works fine on my end.

okiehsch picture okiehsch on 29 Sep 2017

I used 4 different browsers, same setup in uBo, still getting the warning. No idea what's happening.

mapx- picture mapx- on 29 Sep 2017

Tested also in opera, uBo 1.13.8, same behaviour.

mapx- picture mapx- on 29 Sep 2017

I tried with two different machines with different OSes, Windows 10 and Linux (Manjaro), works with both
setups on my end.
Does
meta-chart.com##script:inject(setTimeout-defuser.js, "ubo", 300) meta-chart.com##script:inject(setTimeout-defuser.js, [native code], 15000)
work for you?

okiehsch picture okiehsch on 29 Sep 2017

Your filters are working in chrome 61, 62, opera 48.
Don't work in FF 57 + uBo 1.4.11rc8 (probably because uBo does not read anymore resources.txt ? )

mapx- picture mapx- on 29 Sep 2017

No, Firefox needs another setTimeout-call defused, seems new to me, anyway
meta-chart.com##script:inject(setTimeout-defuser.js, "ubo", 300) meta-chart.com##script:inject(setTimeout-defuser.js, [native code], 15000) meta-chart.com##script:inject(setTimeout-defuser.js, [native code], 0)
works for me and I will have to add
example.com##script:inject(setTimeout-defuser.js, [native code], 0) to uBO-filters, because they do not work, using Firefox, right now on my end, example link:
http://www.post-gazette.com/business/money/2017/09/29/More-parents-are-finding-ways-to-save-money-for-college/stories/201709250142

okiehsch picture okiehsch on 30 Sep 2017

yes, the above 3 filters are working for me too in FF.

mapx- picture mapx- on 30 Sep 2017

There is still the question why
meta-chart.com##script:inject(abort-current-inline-script.js, Promise) does not work for you.
Does meta-chart.com##script:inject(abort-current-inline-script.js, setTimeout) work for you?
If not can you look at the source-code of meta-chart.com to check if we both get served the
same document.
Search for window.promise, you should get two hits.

okiehsch picture okiehsch on 30 Sep 2017

yes I see window.promise twice, see the inline script here:
https://mega.nz/#!WcwkADha!EBXXj3CLeMvAE4SD1MhkzrAbFGqf6ZFqt1S7z3qBM3c

mapx- picture mapx- on 30 Sep 2017

and this filter
meta-chart.com##script:inject(abort-current-inline-script.js, setTimeout)

does not work for me (in chrome)

mapx- picture mapx- on 30 Sep 2017

Well, then I don't know why it does not work for you, they both work on my end, sorry.
I suppose meta-calculator.com also does not work on your end, uBO also uses
##script:inject(abort-current-inline-script.js, Promise) for that domain.

okiehsch picture okiehsch on 30 Sep 2017

meta-calculator.com ...is working fine.

mapx- picture mapx- on 30 Sep 2017

Well, now I am officially without a clue what the problem is on your end 馃槙 .

okiehsch picture okiehsch on 30 Sep 2017

well, no big deal from my part, I arrived here from the other issue (receive-a-sms.com) and I wanted to test it ..

mapx- picture mapx- on 30 Sep 2017

And I realized that I have to add another filter for Firefox users, so it was a productive confusion.

okiehsch picture okiehsch on 30 Sep 2017

@mapx- Can you put somewhere the raw content of view-source:https://www.meta-chart.com/? It's as if you are not served the same thing as us.

gorhill picture gorhill on 30 Sep 2017

@okiehsch @gorhill So filters not needed for Chromium users will be served to them as well? I believe there should be a different list for such issues specific to the workings of Firefox and enabled for default for the users of Firefox.

Just as was the need for uBO Extra for Chromium users.

gotitbro picture gotitbro on 30 Sep 2017

@gorhill here the raw content:

mapx- picture mapx- on 30 Sep 2017

@mapx- do you have Peter Lowe鈥檚 list enabled?
If you have, is the connection to functionalclam.com blocked or not?

okiehsch picture okiehsch on 1 Oct 2017

No, I don't use Peter Lowe's list.
However, with / without that list the same result.

mapx- picture mapx- on 1 Oct 2017

I tested chrome 61, 62 + uBo 1.14.8 + default filters

Well, without that list, which is part of the default setup, I can reproduce your issue and it also explains why meta-calculator.com does work on your end, because there is no connection to limpingline.com via functionalclam.com at that site.

okiehsch picture okiehsch on 1 Oct 2017

right. Now meta-chart is working fine, but ... my test page (axistrivia) still does not (even if functionalclam and limpingline are blocked). However, does not matter.

mapx- picture mapx- on 1 Oct 2017

No, your testpage also works if I block limpingline on my end.
If you go to meta-chart.com with functionalclam blocked, there should not be any
limpingline-request anyway.

okiehsch picture okiehsch on 1 Oct 2017

yes, (again) my fault (I've commented the promise filter for axistrivia).

On meta I can see only functionalclam, on axistrivia I see both of them:
func

mapx- picture mapx- on 1 Oct 2017

We finally have identical results :)

okiehsch picture okiehsch on 1 Oct 2017

well, now I will enable peter lowe's list in all my browsers.

@okiehsch , 1 more thing: could you explain how did you find the necessary parameters for setTimeout-defuser.js (300, 15000) in these filters ?

meta-chart.com##script:inject(setTimeout-defuser.js, "ubo", 300)
meta-chart.com##script:inject(setTimeout-defuser.js, [native code], 15000)

thank you

mapx- picture mapx- on 1 Oct 2017

Well, meta-chart.com is a rather difficult example because of the sheer amount of setTimeout-calls.

  1. Add meta-chart.com##script:inject(setTimeout-logger.js)
  2. Disable script:inject(abort-current-inline-script.js, Promise), because that filter disables
    some setTimeout-calls.
  3. Open your console and go to meta-chart.com

How you find the right parameter can be rather tricky.

And just fyi example.com##script:inject(setTimeout-defuser.js) defuses all setTimeout calls of that site.
