The combined situation

Synthesia is a corporate AI avatar platform with hundreds of stock avatars. Custom avatar creation requires identity verification, which makes it less commonly used for NCII but it has appeared in impersonation cases. When Synthesia output appears on X (Twitter), removal proceeds through the statutory takedown process under 47 USC 223a combined with source attribution to strengthen the legal claim.

Why this combination is high risk

Identity verification for custom avatars limits NCII vector but stock avatar misuse for impersonation remains a documented issue. On X (Twitter) specifically, x surfaces content algorithmically based on engagement, which means ncii content can be rapidly amplified before moderation responds. quote retweets and bookmarks preserve content even after the original is removed.

How removal proceeds

X accepts NCII reports through its dedicated reporting flow and through its DMCA agent. The platform also accepts direct emails to its trust and safety team for high severity cases. Source attribution to Synthesia is documented through synthesia outputs use specific avatar templates with recognizable presentation styles, which strengthens the takedown notice and supports parallel legal action.
