Frequently asked questions
What is an X/Twitter expert witness?
An X/Twitter expert witness provides courts with specialized knowledge about how X works — including content distribution, reach analysis, verification, defamation scope, and platform-native data interpretation. Expert testimony is used in defamation, employment, IP, and harassment matters.
How has X changed since the Twitter acquisition?
Since 2022, X has changed its verification system, modified its algorithmic amplification approach, altered its content moderation policies, and changed its API access for legal process requests. These changes affect how evidence from the platform should be interpreted and what data is available through legal process. Expert testimony is required to explain these platform changes in litigation involving X content.
Can tweets be authenticated as evidence?
Yes, but authentication requires more than a screenshot. Platform-native exports, URL-verified captures with metadata, and expert testimony about provenance are required for reliable authentication. X's content editing and deletion features, as well as account suspension and deactivation, create additional authentication complexity.
When should an X/Twitter expert witness be retained?
As early as possible. X content can be deleted rapidly and account data may be unavailable if accounts are suspended or deactivated. Early retention allows for proper preservation requests and the most complete evidentiary record.
