After joining the mcn backend, can the account be banned if the expert opens a trumpet account?

No. After joining the mcn backend, experts can open a small account. As long as they comply with the relevant regulations of the WeChat public platform, the account will not be blocked. It does not necessarily mean that the account will be blocked after opening it. The MCN backend is a platform that provides services to content creation organizations. It provides organizations with one-stop functions such as member management, data analysis, and resource allocation, helping organizations improve their operational capabilities and better build their high-quality account matrix.
