Remove Civitai content from Tumblr

The combined situation

Civitai is the dominant hosting platform for Stable Diffusion fine tunes and LoRA adapters, including a large catalog of celebrity and public figure LoRAs that enable NCII generation. When Civitai 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

Civitai hosts thousands of LoRA models trained on identifiable individuals without their consent. Each removed model prevents future generation rather than addressing existing content. 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 Civitai is documented through civitai itself does not generate images, but hosts the model files used by other tools, which strengthens the takedown notice and supports parallel legal action.
