Sarcasm aside, are there any metrics whether a blocking automated popup actually increases any kind of conversion? Because from my experience it causes confusion and it hides the content you are trying to see. It's just annoying. I usually close the tab immediately instead of closing the popup, I don't expect any useful content from anyone that tries to force me into signing up to their lovely newsletter or something this way. It just shows you're stupid and don't give a shit about your users' experience.
