Can social media posts be used as evidence in a Tennessee case?

Social media evidence fails in Tennessee cases far more often over collection than over content. The post itself is frequently damning. The problem is that the party offering it cannot prove the account belongs to the person, cannot show the post existed in the form claimed, or obtained it in a way that raises its own problems.

What can you lawfully collect?

Anything publicly visible without logging in as someone you are not. Public profiles, public posts, public photographs, comments on public pages, business pages, and content a person has chosen to make visible to anyone. This is straightforward research and there is nothing improper about it.

What crosses a line?

• Creating a fake profile to send a friend or follow request and see restricted content
• Using someone else's account, with or without their permission, to view private material
• Guessing or using credentials to log into an account you do not own
• Asking a mutual friend to pull content from a private account on your behalf
• Anything that amounts to unauthorised access to a computer or account

The practical cost of these methods is bigger than the legal exposure. Evidence obtained by pretext hands the other side a story about your conduct that is far more interesting to a judge than whatever the post said. It converts a case about their behavior into a case about yours.

How do you authenticate a post?

The recurring obstacle is proving the account belongs to the person. Tennessee courts, like most, look for circumstantial indicators rather than accepting a name at face value: distinctive content only that person would know, photographs of them, references to events in their life, account details linked to their phone or email, or an admission. A screenshot of a profile with their name on it establishes very little on its own, because anyone can create such a profile.

What is the right way to capture it?

Not a phone photograph of a screen, and not a cropped screenshot. Capture the full page with the URL bar visible, the timestamp visible, and the surrounding context intact. Record the date and time you captured it and the account you were logged in as, if any. Where the content matters enough, an investigator can capture it with documentation of the method, which gives you a witness who can testify to the collection.

Can you delete your own posts once a case starts?

This is where people damage themselves most. Once litigation is reasonably anticipated, deleting relevant content can be treated as spoliation, and a Tennessee court may respond with an adverse inference — effectively instructing the jury to assume the deleted material was unfavourable. The deletion frequently does more harm than the post would have. Tightening privacy settings going forward is a different matter from destroying what already exists.

What about content that has already been deleted?

Deleted does not always mean gone. Archived copies, cached versions, screenshots other people took, and content reposted elsewhere all survive independently. Platforms also retain data beyond what users see, which is reachable through lawful process in a pending matter but not by an investigator's request.
