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 Tumblr, 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 Tumblr specifically, tumblr reblogs create persistent copies of content across hundreds of unrelated blogs. a single original post can have thousands of reblogs, each requiring a separate url in the takedown notice.

How removal proceeds

Tumblr accepts NCII reports through its content removal form and through its DMCA agent. The platform's 2018 adult content ban remains in effect, which means NCII reports also benefit from policy enforcement against any sexual content. 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.
