Is it illegal to copy someone else's circle of friends for recruitment?

Whether it is illegal to copy other people's circle of friends for recruitment depends on the specific situation. Generally speaking, if you use other people's words, pictures, videos, etc. As your own recruitment information in the recruitment advertisement, without the authorization or permission of the original author, it may infringe copyright or intellectual property rights and other laws and regulations. In addition, the use of false information and false propaganda in recruitment may also involve illegal acts such as fraud and false advertising.

However, due to differences in regions and laws and regulations, the specific situation may be different. I suggest you consult a professional lawyer or legal consulting agency to understand the specific legal requirements and regulations. This can ensure that you abide by relevant laws and regulations during the recruitment process and ensure that your behavior is legal and compliant.
