My Netflix profile is my sanctuary. Nobody can get in and mess around with my algorithms or my saved shows, but they can get into their own profile and watch whatever they want. Currently, the only people who have a profile on my account other than me are my parents, and they mostly use it just to watch The Great British Bake-Off.
Unfortunately, Netflix might be rolling out new ways to try to make that a paid feature, not a free option on every account.
