About exception filters in EasyList
Posted: Fri Jan 13, 2017 2:54 am
Hello all,
I am a newly registered user of this forum but have been aware of it for many years. I never actually bothered making an account until now.
The purpose of this thread is to point out continual exploits pertaining to exception filters included in the EasyList subscription package. I’ve used EasyList for quite some time but have grown weary of its more than occasional false-positive “exception rules”. Please note that I don’t allow non-intrusive ads and I don’t allow “acceptable” advertisements to load.
After browsing around I will intermittently encounter an absurdly flashing ad banner or other disgusting/adult themed advert. I will quickly scan through the list of blockable items on the page and identify the source of the advertisement. More likely than not, the source of the advertisement is being ALLOWED TO LOAD from an “exception rule” in the EasyList.
After blocking the aforementioned URL, I will return to the website in several weeks to see that the ad banners have returned and are USING ANOTHER (but entirely different) EXCEPTION RULE from EasyList.
It’s important to point out that these aren’t just occasional false positives. These URLs are used in a timely manner to inject advertisements into the page through scripts or other methods. The fact that they have been purposely allowed to load in the first place is malicious.
It can be concluded that certain sites are manipulating the exception rules in EasyList in order to continue loading their advertisements. After a couple of weeks the site probably updates itself to use a different exception and load its advertisements from that accepted source.
Whether EasyList is knowingly or unknowingly allowing these obviously false exception rules into their list is unclear. However, it is clear that the EasyList rules need to be immediately reevaluated or disabled.
