Marian Kočner's Threema is an underworld offering a wide assortment of the worst things that influence and proximity to power can activate. People entered the app deliberately, disregarding what Dante told us about hell: Abandon hope all ye who enter here.
Quite the contrary: They hoped that they were part of a new caste, one to whom nothing could happen, thanks to their ties to influential people.

They procured services they would be ashamed to pay for openly. And they provided information to Kočner, the kind of information they should have passed on to the police instead.
