What the court held

A printout of a profile page from a Russian social-networking site was admitted without adequate authentication under Rule 901, because the government offered no sufficient basis to conclude the page was the defendant's rather than one created by someone else. The error was not harmless and the conviction was vacated.

Why

The court observed that all the identifying information on the page was known to the cooperating witness and probably to others, some of whom had reason to create a page falsely attributed to the defendant. Nothing in the record showed the defendant even had an account on the site, let alone that this was it, and there was no evidence that the platform required identity verification to create a page. The page mattered only if it was his, which is what made the authentication failure decisive rather than technical.

Our reading — not the court’s words

Why this matters in practice

Vayner is the leading federal appellate authority for excluding a social-media exhibit, and the key move is its focus on who else could have produced the artefact. That is the question an examiner should be asked in any attribution dispute: not whether the content matches the person, but whether anyone else had the same information and a motive to use it. The court's note that the platform required no identity verification is also a reminder that platform-level facts are part of the authentication record.
