Remove Unstable Diffusion content from Tumblr

The combined situation

Unstable Diffusion is a community oriented explicit image generation service that originated as a Discord community for uncensored image generation. When Unstable 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

Community structure produces continuous model improvement focused on bypassing content filters in mainstream services. 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 Unstable Diffusion is documented through unstable diffusion uses community trained models with variable rendering styles, but service generated images carry platform metadata, which strengthens the takedown notice and supports parallel legal action.
