Netflix question?

I have had Netflix access from my aunt for a year and a half because she has a family account, and four different households have a user account (one of which is me).

That's actually forbidden, and my aunt said about 2 months ago that she was going to cancel her subscription because she heard that Netflix checks IP addresses or something and that you might have to pay a fine because of it.

Now I'm back on Netflix and I still have access to everything… All four user accounts are still listed in the menu, and I can easily go to mine and watch stuff.

And the subscription was canceled a month ago
