What is the appropriate label for content that may not be suitable for a public space?

The most suitable label for content that may not be appropriate for a public space is "Viewer Discretion Advised." This label effectively communicates that the content may contain elements that some viewers might find unsuitable for various reasons, such as sensitivity to specific topics, language, or imagery. It encourages individuals to assess their comfort level with the content before viewing, making it a thoughtful consideration for those in a public setting where diverse audiences may be present.

The other labels, while they may convey some level of caution, do not encapsulate the idea of viewer choice and personal judgment as clearly as "Viewer Discretion Advised." For example, "Not for Everyone" implies exclusivity without asserting that viewers should consider their own context, while "Potentially Offensive" could be too vague and might not cover all aspects of what makes content unsuitable in a public setting. "Public Space Warning" suggests a more generic disclaimer without a personal responsibility aspect, which is central to the concept of viewer discretion.
