Saying the word 'Paragon' out loud is a crime, and everyone knew that.
That is why they created a workaround.
In the past, merely saying the word Paragon would instantly call down the heavenly divine punishment on you and obliterate you if you could not defend against it.
Billions died due to this.
Klaus personally witnessed it many times in the past. That is how seriously the heavens took his name and his threat.
Of course, that was when the heavens thought that saying the name Paragon gives him power. They also have no way to kill him, so they were merely killing people in the masses just to see if his authority would diminish.
To many, that word was taboo and shouldn't be spoken.
Later, that rule changed. Now, instead of instant obliteration, it adds to your bad karma and waits for the time when your tribulation descends.
