That's true, of openAI accounts at least, good point. I think i linked mine to a work phone that I don't use for anything apart from receiving on-call calls.
Although i've been running a ChatGPT 4 space via hugging face that doesn't need a AI key or an account, so there is nothing linking it to me.
There are a few you can find by searching ChatGPT4 if it gets busy, also this allows you to run GPT 4 for free which is only for plus members right now.
I'd be interested in how GPT answers that question.
