The document defines and discusses facelessness in social media. Facelessness refers to anonymity online, where users can be anonymous and their real identities unknown. It has three definitions - having no face, being remote and impersonal, and being anonymous. While anonymity allows insulation from repercussions, it can enable negative behaviors like insults, cyberbullying, and fraud. Complete anonymity is nearly impossible due to technology that can trace IP addresses and devices. The document examines both benefits and risks of facelessness in social media.
