Profile or post
A post, video or comment link may not match the profile example in the menu. Open the author’s page and inspect its address. Do not truncate a URL arbitrarily; the path can identify the intended object.
Names are not unique
Display names, avatars and descriptions can repeat. A similar profile still needs independent verification. Do not transfer information between accounts solely because they look alike.
Availability and recency
A page may have changed or become unavailable since a record was created. A search result does not promise access to private content. Separate what is visible now from what an older source reports.
