We are indeed serious and it is not arrogance at all by rather feeling hurt to be called scammers when we are work so hard on our project.
If you're hurt and you cannot defend your project without threatening people then you don't deserve to be a project developer, this is not how a CEO and project developer behave you don't shut people with a suit, you defend the legitimacy of your project by correcting your error and showing the strong point of your project check out successful projects they don't thrive suing people.
