Adblock Detector & Anti-Adblock Script Generator

This utility serves a dual purpose: first, as a client-side diagnostic tool to verify the presence of active content filtering agents (Adblockers) in the current session; and second, as a production-grade code generator for webmasters seeking to mitigate revenue loss. Ad-blocking software typically operates by intercepting network requests matching specific RegEx patterns or by injecting CSS rules to hide DOM elements with specific class names (e.g., .ads, .banner).

Understanding the "Aggression Level" of a blocker is critical. Simple filters may only hide visual elements (visibility: hidden), while aggressive heuristics block the HTTP requests entirely (ERR_BLOCKED_BY_CLIENT). This tool tests both vectors to provide a granular diagnosis. The generated scripts utilize the same logic, encapsulated in a namespace-safe closure to prevent conflict with existing site architectures.

The detection algorithm operates on a boolean logic gate combining multiple heuristic signals. The final state S is determined by the union of DOM interference and Network interference.

Where h(el) represents the computed height of the bait element, and the network request attempts to access a resource matching standard blocklist patterns (e.g., /pagead/).
