I feel like there are a lot of people that don't understand hypnosis and think "Hypnosis is magic!" And they don't actually know how to hypnotize someone.
And I feel that the email slave file gives people that don't understand hypnosis the ability to give suggestions like a hypnotist without the need to actually understand hypnosis. Thus they all flock to it thinking they can become magic.
The way that email read it almost looked like it expected them to actually act out the scenario, but that the laws of physics would comply with their suggestions.
