Or 5. It holds 6 people... 4 € per person best case. As for now, they aren't enforcing same household sharing only, like Netflix do. I can't tell you about the future.

Also, not to support such behaviour, but if you aren't made of money, I'm totally okay with you teleporting to Argentina, subscribing to YT Premium at maybe 5 $ a month, and teleporting back to never go there again. That doesn't require an argentinian CC.

I'm not sure about legal technicalities, but I do know that it currently works. Personally, I don't risk it if they ever decide to ban associated accounts, because u know, they totally can refuse to service you, if they were to feel like it.
