It seems strange that you would speak English, but then use the French spelling of Defamation.
Why would you delete this thread?
Wouldn't it be good evidence for the investigation you're getting started on everyone that criticizes you, your methods of business or leaves you a bad review?
If I was you, I would stop making illegal threats to knowingly defraud any authority's resources; I imagine if they did some digging into you they would love what they find, and you wouldn't want to incriminate yourself! What is that old saying? "Don't throw rocks in a glass house" or something.
Strange that you can understand this :
Op you cannot sue Lauda if he didn't do anything illegal, give red trust isn't illegal
Yet, think that this is somehow applicably criminal?
