I feel like the only protection against AI in general, not just for tickets, is trust.
If I trust you, you can do whatever you want as long as I trust you.
If I don't trust you, you can do whatever you want; I will just block or ignore everything you do.
It's when we try to interact with random people that we get problems. Doing that will become less and less possible the more AI grows. We will have a future where trust is very important.
