In Google's OAuth 2.0 for TV and Limited-Input Device Applications page, https://developers.google.com/identity/protocols/oauth2/limi..., it says:

"Note that there are limits on the number of refresh tokens that will be issued; one limit per client/user combination, and another per user across all clients. You should save refresh tokens in long-term storage and continue to use them as long as they remain valid. If your application requests too many refresh tokens, it may run into these limits, in which case older refresh tokens will stop working."

Maybe you could try issuing thousands of OAuth refresh tokens (or more) for your account, in the hope that it will hit some internal limit and automatically revoke the one stored inside that Smart TV?

I think the risk of getting banned due to misuse is not worth it... But I like your hacker mentality!
