This is a mindset I cannot understand - it's quite within most developers reach that they could scrape and reproduce airbnb. It's quite within most people's ethics to realise you could then take money off people who did not spot it.

But to set up a criminal SaaS, that other criminals pay to use, and to somehow think you cannot be found or caught?

It just seems that this sub world has been allowed to develop and evolve for soooo long they have stumbled upon whole eco systems.

It's going to be hard to uproot.
