Netflix and perental controls

[P-Jay]

Perhaps I'm missing something obvious here?

I've got a 9 year old that simply cannot be trusted with any sort of electrical device - given the chance he'll delete 'child friendly' accounts, and start his own (usually with some desperately uncool name with the word 'cool' in it) completely free of restriction - it's been a Devil's job getting his Tablet, PS3 and the account on the family PC to the point where he won't accidentally develop a taste for Mexican Beheadings or Eastern European Scat Videos. I can monitor everything he does on any of those and indeed what he searches for on Google.

But Netflix, on the other hand... I set up an account for My Wife and I, and one for 'Kids' which restricted him to PG and under stuff - and of course he deleted this and set up his own JnrJayisthecoolestestev4r account - and 'forgot' to restrict the content - nothing sinister but he loves a US Teen drama and it makes for an INCREDIBLY irritating kids to live with, what with all the 'attitude' and throwing shade whatever that is. So I changed it back, and this stopped him for about 8 seconds before he realised all he has to do it click my name instead of his on the "whose watching" page and carry on - as far as I can see, unless you're in Germany there is no way of putting a password request or PIN lock on this - it's the self-service checkout of parental controls - useless.

Any ideas?

Thanks for the advice, I hadn't actually considered discipline or simply telling him not do to it - I can't believe I made such and oversight - it's probably explains why I found him trying to secure passage to Syria this morning.

I've ordered a large cane online.
