ONE TIME I got drunk and thought it would be funny to watch a kids movie, some Pixar shit. I got bored and shut it off after 20 minutes. Apparently that's all it takes. The INSTANT anything kid friendly flickers on your screen, your account is apparently immediately and permanently poisoned with the "A child lives in this house" tag, and from then until the end of time you have to engage in an extra, meaningless button press every time you log into Netflix.
I'm using a smart TV with a Netflix ap built in, but I see it on my PS3 too. I logged in to my account on the website, but there's no way to disable anything. It hardly offers any interface options.
