Preventing scam before losing money on a course in an online world where everyone is a luxury car show, we must distinguish whether the rich are rich from hard work, building a real business, or simply creating the illusion to sell online courses, some living a broken life, but actually borrowing photos and posts to entice buyers to buy expensive courses that promise exaggerated results.Article illustration: Preventing fraud before losing money on the course.People who post often like to make long-term fortunes, not show up, and people who post often like to brag about big cars or houses, but actually owe a lot to maintain their image, like people who post every day but do not do business seriously, eventually sell "quickly rich" courses to earn money. Too little to say. Too much to say: Ask about life before you tell your story. Don't show up. Don't show up: Real wealth doesn't need to be proven by pictures. Use security: buy money back, not show money. Don't show up. Don't show up. O'Wiki often overdoes advertisements like "go to the mall" to get paid.
