i would take the deposit and use it to hire freelancers to do some kind of Die Hard 1 / Die Hard 3 / Under Siege sort of situation. or just get everybody to ingest/inhale ricin lol. just kidding, i would never do that because it's illegal and i am a good boy.
i've heard of people doing that kind of thing, like invoicing some giant multinational company for something after they've figured out the address for accounts payable or whatever and getting away with it. but i've also heard of people getting caught in an audit and hit with fraud charges because it went through the US mail, which above a certain amount is a felony. but, respect the grift lol.
