When a Facebook comment is hidden, it becomes invisible to anyone except the person who posted it and their friends, as well as the page administrator or moderator. For instance, if a user posts a disrespectful comment on a company’s Facebook page and the administrator hides it, only the user who posted it and that user’s Facebook friends will be able to see the comment. Other visitors to the page will not be aware it ever existed.
This action is useful for managing online discussions and maintaining a positive community environment. It allows page administrators to address inappropriate or off-topic content without necessarily deleting it outright, which could potentially escalate a situation. Historically, this feature evolved as a way for online platforms to provide more nuanced content moderation tools beyond simple deletion or banning.
