Why are you hiding parts of article text with a subscription form saying "Want LARB in your inbox?". I want to read your thing first, without being disturbed.
However, I never understand popups/modal windows on top of articles I'm actively trying to read, spawning after I scroll down the page. If anything, it will rather irritate me for the interruption rather than succeed in upselling me to subscribing to a newsletter from a website I've only just visited for the first time.
