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 TikTok, 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 TikTok specifically, tiktok's recommendation algorithm can drive a single video to millions of views inside 24 hours. re uploads using the duet and stitch features create derivative content that requires separate notices.

How removal proceeds

TikTok accepts NCII reports through its in app reporting flow and through its dedicated trust and safety email. The deepfake reporting category is processed in a separate queue and has the fastest turnaround. 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.
