Beyond the "IStaunch" website, there is also a claim of a related portable browser extension called "I Can See You" that promises to unlock profile and cover photos of locked Facebook users. These tools are often marketed as a way for users to view content that is otherwise inaccessible, creating a strong lure for the curious.

When a user sets their profile to "Private" or "Friends Only," that preference is enforced directly on Facebook’s enterprise servers.

The most legitimate way to view a private profile is to connect with the person directly.
