How can you spot a scammer by the way they talk, type or write emails etc.?

The deal is usually too good to be true. Other than that. Maybe ask where they are from. If they are from India, Nigeria or Russia they might be scammers. If they lie about where they are from you might be able to tell. Spelling mistakes. Also wanting to get to know you by replying really fast can be a clue. It’s sad but it’s true. Scammers are going to hell when they die. I hope. If there is a hell then I would assume they would go.
