The combined situation

Stable Diffusion is the foundation model for most current explicit image generation. The base model has safety filtering, but uncensored fine tunes and LoRA adapters that target specific individuals are widely distributed. When Stable Diffusion 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

Person specific LoRA adapters trained on a victim's photographs enable repeated NCII generation. LoRA file removal from hosting platforms is a critical and often overlooked lever. 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 Stable Diffusion is documented through stable diffusion outputs across versions have known visual fingerprints including characteristic noise patterns in flat regions and recognizable hand and finger artifacts, which strengthens the takedown notice and supports parallel legal action.
