Ah, now that really is random! One idea for sifting parking pages that comes to my mind is using image recognition. I can easily tell when something is a parking page by looking at it, I bet you could get an ML model to do so with pretty good accuracy too. There is a class called fast.ai [1] which I personally found to be an amazing introduction to machine learning / deep learning. The first hour and a half course gets you using their library to make an image classifier that can differentiate dog and cat breeds. I bet by simply gathering training data (sites that are and are not parking pages) and reusing the same architecture used in that first class you could train a model that does a pretty good job of it. Once you could classify pages you could just pre-compute a large list, classify, throwaway all the parking pages, and make the remainder available to your user. 1 - https://www.fast.ai/ https://www.fast.ai/
