So, they were in some sort of trance when they programmed the calls. They were sleepwalking perhaps?
You do know that ignorance of the law is never an excuse, right?
I don't know what they knew or thought they knew. I know that the law you guys cited says in specific that the only thing that elevates this to a "criminal" fine is the qualification that they "knowingly and willfully" did this. So... I would say that the law directly contradicts your claim that ignorance is no excuse. It specifically says that they had to know they were breaking the law in order for this to be criminal.
Therefore, if they were ignorant of the law, they are still guilty of breaking it, yes, but not to rise to the level of a criminal offense.
This still is not anywhere near criminal activity. Yet.
