Which of the following is NOT an option for Facebook Gating?

The reason "Single User" is identified as NOT an option for Facebook Gating lies in how Facebook's targeting and gating features are structured. Facebook Gating typically allows brands to target content to specific demographics or locations.

The options for gating, such as "Everywhere," "Cities," and "States," focus on broader geographical scopes, enabling brands to manage access to their content based on a user's location. For instance, "Everywhere" indicates that the content is available globally, "Cities" allows for targeting individuals in specified urban areas, and "States" lets brands restrict content access to users in particular states.

On the other hand, "Single User" suggests a level of targeted access that doesn't align with the intent of Facebook Gating. This option implies individualized control that Facebook does not support in its gating mechanisms, as gating is primarily meant for larger groups based on shared characteristics rather than for isolating access to individual accounts. Thus, it becomes clear why "Single User" does not fit into the established methods for Facebook Gating.
