The act of concealing a Facebook comment from public view, specifically preventing the original commenter and their mutual connections from seeing it while still allowing the comment to be visible to the person who made the post and their friends, does not generate a direct notification to the commenter. The commenter will remain unaware that their contribution is only visible to a limited audience.
This feature serves as a moderation tool, enabling users to manage the discourse on their posts without resorting to outright deletion, which could potentially escalate conflict. It allows for the subtle removal of offensive or irrelevant content while preserving a semblance of open communication. The implementation of comment hiding reflects Facebook’s ongoing efforts to balance free expression with the need for a civil online environment.
