The site utilizes a simple inline script located at the bottom of the for adblock detection. It attempts to load an external ad tag (bnctag.js) and triggers the overlay if the request fails.
Relevant Code:
async function runAdCheck() {
const adBance = document.createElement('script');
adBance.src = 'https://js.ssp.bance.jp/bnctag.js';
adBance.onerror = async () => {
checkScriptOnError();
};
adBance.onload = () => {
checkScriptOnLoad();
};
document.head.appendChild(adBance);
}
runAdCheck();
