Yes, anything that makes you earn money by brushing your reputation is mostly fraud.
Brushing reputation is an immoral and illegal act, which violates the regulations of many platforms and may lead to your account being banned and even facing legal responsibility. At the same time, this kind of behavior may also make you fall into the fraud trap, because fraudsters usually cheat you of your money by brushing their reputation.
Fraudsters may post false recruitment information on social media, advertisements or emails, claiming that you can make money just by brushing your reputation. They may promise you a high commission or bonus, but in the end you may find yourself cheated.
Therefore, if you receive similar recruitment information or invitation, you must be vigilant and don't trust each other easily. If you are not sure whether a recruitment information or invitation is true, you'd better verify it through official channels or consult a professional.
In addition, if you have become a victim, you must take timely measures to protect your property. You can contact relevant institutions or platforms to report fraud, or you can report to the local police. At the same time, you can also report fraud to your bank or payment platform and ask them to take corresponding measures to protect your account security.
In short, always be vigilant and don't trust strangers or unreliable information easily. If you want to make money, you'd better go through legal and reliable channels, and don't try to brush your reputation and other illegal acts easily.
