Ad Blocking Detector Implementations
A list of websites that use ad blocker detectors, broken down by the checks they run. A "Bait Check" involves creating a container with a class name/id formulated to be detected by filter lists (the Bait Name) and then uses a series of functions to check whether the container has been blocked (the Bait Functions). A "Load Error" involves directly checking whether an external resource has been loaded; we note the resources loaded and the type of check used to detect the failure to load. A "Variable Check" involves loading a script designed to be blocked by filter lists. The script gives the variable a value, and that variable is checked in the main code to ensure the target script has been loaded.
