19. Read Reviews

If a company is scamming people, there’s a huge likelihood that people who’ve been scammed by them in the past – or even people who didn’t fall for their scams – have written about it online.

Whether or not the bogus company in question has a web presence of their own, there will be bad reviews online. So simply type in the company’s name plus the word “reviews” into your search engine and any relevant feedback will undoubtedly appear in your search results.
