What is prohibited regarding your license?

The prohibition on posting photocopies of your license is rooted in maintaining the integrity and authenticity of the licensing process. Licenses serve as official documentation of an individual's qualifications and the legal authority to practice. By only presenting the original license, it ensures that the information is accurate and current, preventing issues such as forgery or misrepresentation.

Photocopies can easily be altered or misused, potentially leading to fraudulent activities. Therefore, using only the original license in any public display or professional context is mandated to avoid confusion and protect both the licensee and the public. The other options, while also potentially problematic in their contexts, don't specifically address the same level of risk regarding integrity and authenticity that posting photocopies does. For instance, while exchanging licenses or signing on behalf of another might violate ethical guidelines, they don't compromise the foundational validity of the licensing system like displaying a photocopy would.
