Netflix today added a feature that allows you to set a four-digit PIN on your user profile. While the feature was baked into a new set of parental controls and is ostensibly to stop kids from accessing content meant for grown-up persons, I know the real reason: to stop people from messing up your recommendations.

I’ve ‘lent’ my Netflix password to so many people over the years, I’m pretty sure every other person I know is using my Netflix password. For all I know, they’ve given that password to more other people. It would explain why I have recommendations like ‘exciting foreign language murder mysteries for children and families.’ Okay, that’s not a real thing, but you get my point.
