Based on my own interactions with Google, this seems the most likely. We have a niche educational/medical app directed to children, to help them understand their treatment with kid-friendly characters talking to them on their level. The app was taken down because some form had been added to the Google Developer console (the backend of google play) years after we had published and we hadn't answered it. We only found out because someone else in the company heard from a customer that they couldn't find the app online. A cursory glance showed that the app wasn't listed any more. After we logged in to Google Developer console, and explored through google's ever changing menus and product renames, we had found an alert to fill out a form. We only had to tick no to a handful of questions on the form and submit it. The questions were things like: "Is your app a news app?", "Does your app feature sexual content?", etc... All things that google should have been able to figure out based on the rating stuff we had to fill out when the app was first published. About 2 days later, the app was available again.
