DisablePingOnReply.js

// If you want to see an explanation of the code, please refer to the previous revisions
(this.disablePingToDefault = () => {
    this.disablePingToDefault.interval = setInterval(() => {
		if (location.href !== this.disablePingToDefault.currentUrl) {
			if (this.disablePingToDefault.observer !== undefined)
				this.disablePingToDefault.observer.disconnect();
			else {
				this.disablePingToDefault.observer = new MutationObserver(() =>
					document.querySelector('div[class*="mentionButton"]')?.click()
				);
			}
			
			let channelTextArea = document.querySelector('div[class*="channelTextArea"]');
			if (channelTextArea !== null)
				this.disablePingToDefault.observer.observe(channelTextArea, { childList: true });
			
			this.disablePingToDefault.currentUrl = location.href;
		}
	}, 50);
})();

// This function changes to original setting; If you want to change it that way, you can run 'enablePingToDefault();' into the console.
this.enablePingToDefault = () => {
    clearInterval(this.disablePingToDefault.interval);
    this.disablePingToDefault.observer.disconnect();
    delete this.disablePingToDefault;
    delete this.enablePingToDefault;
};

아이디어가 참 좋으시네요 선생님
