Collecting Online Evidence? Don’t Let Screenshots Sink Your Case

Imagine for a second that you need to collect evidence from someone’s Facebook or Twitter account. Like a surprising number of criminals, the person has just posted something incredibly incriminating that could really help your case. However, there’s also a good chance that they’ll come to their senses and delete the post. The evidence can disappear at any moment—so you need to act quickly.

What do you do? 

If you’d simply take a screenshot, you are not alone. Many plaintiffs, investigators, regulators, and even legal professionals resort to taking screenshots. The reason for this is simple: it’s the obvious solution to a tricky problem. There simply aren’t that many ways to preserve a digital copy of a social media post that exists exclusively within an online platform. While you can simply create a copy of a Word, Excel, PDF, audio, or video file, a social media post doesn’t have that option.  

Uhm, Do You Have the Metadata?

So, a screenshot can seem like a rather elegant solution to the problem. But while this approach will allow you to capture whatever’s on screen, it does introduce its own challenge. Because a screenshot is transforming a social media post into a simple JPEG, it strips it of metadata and makes it impossible to authenticate.

Metadata provides information about digital data. In other words, it’s the data about data. When it comes to a social media post, it would include information about the author of the post, the message type, post date and time, versions, links (un-shortened), location, likes, and comments. (To learn more, read our blog post, What Is Metadata? And Why Is it Important?)


Without this metadata, there is no way to prove that your JPEG copy accurately represents what was originally posted on the social media platform. All you have is an image that could have been Photoshopped or manipulated in some other way—and a court, not to mention your opposing counsel, won’t be satisfied with that.

Social Media Evidence Denied in Court

While it has taken some time for courts and the legal sector to get a handle on social media content that’s dynamic and real-time, it’s fair to say that screenshots are increasingly being viewed with suspicion. Where it was once relatively common to submit a screenshot into evidence, it’s now becoming a risky strategy that could sink a case.

One example is Moroccanoil v. Marc Anthony Cosmetics. This case, which was argued in front of a federal district court, was centered on trademark infringement and unfair competition of the word “Moroccanoil.” 

Moroccanoil (the company) had registered the word with the United States Patent and Trademark Office (USPTO). Marc Anthony Cosmetics argued that the words “Moroccanoil” and “Moroccan oil” were used interchangeably by consumers as general terms, and Moroccanoil therefore couldn’t  trademark it. 

To support this argument, Marc Anthony submitted screenshots of a Facebook page that illustrated how customers used these words. Unfortunately, the court ruled that the Facebook content could not be entered into evidence, since there was no way to prove that the screenshots were an exact copy of what existed on the live Facebook site. In other words, there was no way to authenticate the screenshots.


Another example is United States v. Vayner. During the trial, a printout of a page on (a Russian site similar to Facebook) was entered into evidence. The defendant's legal team objected, claiming that the page had not been properly authenticated, and that there was consequently no proof that this was in fact his page. 

The court agreed and the evidence was deemed inadmissible, but this decision was later overruled by a district court who argued that it was reasonable to assume that the page belonged to the defendant. 

However, the story didn’t end there. The U.S. Court of Appeals for the Second Circuit again overturned the ruling, arguing that there was no way to prove the authenticity of evidence. The court said that “the mere fact that a page with [the defendant’s] name and photograph happened to exist on the Internet at the time of [the investigator’s] testimony does not permit a reasonable conclusion that this page was created by the defendant or on his behalf.” 

Cases like Moroccanoil v. Marc Anthony Cosmetics and United States v. Vayner underscores the importance of proper collection and authentication methods. Simple printouts and screenshots are not good enough.

The Sedona Conference & Social Media

Another respected legal entity that has been advocating for a more sophisticated approach to social media is the Sedona Conference. 

The Sedona Conference is a research and educational institute dedicated to the advanced study of law and policy. It focuses on the areas of antitrust law, complex litigation, intellectual property rights, and data security and privacy law. 

One of its seminal publications is The Sedona Conference Primer on Social Media, which received a second edition in 2019. The preface of the latest version explains the reason for its creation: “The need for an updated Primer was essential given significant advances in social media technology since we published the first edition of The Sedona Conference Primer on Social Media in December 2012. The proliferation of messaging technology and its usage—on traditional social media platforms and in mobile messaging applications—have created preservation, production, and evidentiary challenges that counsel should learn to recognize and address.”

Predictably, The Sedona Conference specifically addresses the use of screenshots and other static images in its social media primer. The document states that:

“Some practitioners resort to capturing static images of social media data (i.e., screen shots and PDF images) as a means of preservation, with courts often permitting the use of such evidence at trial. Printing out social media data has its evidentiary limitations, as a static image does not capture the metadata of the image, other than whatever information may be viewable as part of the screen shot. As a result, static images may result in an incomplete and inaccurate data capture that is hard to authenticate, except on the basis of the personal knowledge of a witness. Social media may also contain data and content, such as video, that cannot be properly collected in the form of static images. In addition, social media outlets use different interfaces to display content, further complicating efforts to create standardized snapshots. Any such collection will most likely be a visual representation that does not include metadata, logging data, or other information that would allow the content to be easily navigated and used.”

In short, a screenshot has three problems. First (and most crucially), it lacks the hash values and metadata needed to prove authenticity. Second, it lacks context and gives you no real understanding of how social media content is structured or presented. Finally, it cannot capture related video that’s likely needed to understand the purpose and context of a post.

The Automated & Defensible Alternative to Screenshots

So, if screenshots aren’t the answer to social media evidence collection, what is? The Sedona Conference highlights the value of turning to vendors that are able to provide dynamic capture with metadata. “Vendors have developed technology to allow certain content to be collected in a way that preserves the content and captures various metadata fields associated with social media data. Properly captured, these metadata fields can assist with establishing the chain of custody and authentication. They can also help to facilitate more accurate and efficient data processing and review.”
