There is no such word. Even if there is it would be trivial to create a bot that avoids this.
Passports are the only practical way to ensure that I’m talking to a human. Do you have a better idea?
If I think you're a bot I'd ask you to say the word. The word exists and it works every time. No one is going to train a foundation model just to say the word, it's too expensive.
Prompt injection can be mitigated but not this prompt rejection.
