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 iMessage, 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 iMessage specifically, imessage group chats can include up to 32 participants and content can be forwarded to additional chats with one tap. read receipts and typing indicators provide attribution that supports law enforcement subpoenas.

How removal proceeds

Apple accepts iMessage NCII reports through its Communication Safety reporting flow. The iOS 17 sensitive content warning system can also be used to flag content for review. 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.
