If an algorithm knows exactly who you are, then it knows how you think, and it knows what sort of content will manipulate you politically. And right wing political content is profitable. It's called the alt right pipeline. Most people have some kind of argument that will manage to radicalise them to any position you can name. Through correlative learning, an algorithm will look at how people like you changed their views, and it'll send you down the same path. It's easy.
