What would be an example of 'Hidden Elements Detection'?

Hidden elements detection involves checking if certain elements associated with ads are hidden or not present on the page. Here's a simple example using JavaScript to demonstrate this concept:

// Example ad container element ID
var adContainerId = "adContainer";

// Check if the ad container element is hidden or not present
var adContainer = document.getElementById(adContainerId);

if (adContainer) {
    // Check if the ad container is visible
    var isAdVisible = adContainer.offsetParent !== null;

    if (isAdVisible) {
        // The ad container is visible, indicating that the ad is not blocked
        console.log("Ad is visible");
    } else {
        // The ad container is hidden, indicating a potential AdBlocker
        console.log("Ad blocked by AdBlocker");
} else {
    // The ad container element is not present on the page
    console.log("Ad container not found");

In this example, it assumes that the ad is wrapped in a container element with a specific ID (adContainerId). The script attempts to find this element using document.getElementById. If the element is found, it checks whether it is visible on the page (offsetParent !== null). If the element is visible, it logs a message indicating that the ad is not blocked. If the element is hidden, it logs a message indicating that the ad might be blocked by an AdBlocker. If the element is not found at all, it logs a message indicating that the ad container was not found.

Again, similar to other detection methods, this is a basic example, and real-world implementations may involve more sophisticated techniques. Additionally, users can find ways to circumvent such checks, so these methods are not foolproof. Responsible and privacy-conscious development practices should be followed when implementing such checks on websites.
