Remove NovelAI content from Mastodon

The combined situation

NovelAI is a paid image generation service that originated as a text generation platform. The image generator supports explicit output and was an early target of leaked model weight redistribution. When NovelAI output appears on Mastodon, 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

The 2022 NovelAI weight leak created a long tail of derivative models that continue to produce explicit content using the original training characteristics. On Mastodon specifically, federated content spreads across multiple instances through reposts and replies. removing from the originating instance does not remove from the cached copies on every instance that federated the post.

How removal proceeds

Mastodon is federated across thousands of independent instances. Removal requires identifying the specific instance hosting the content and contacting that instance's admin directly. Source attribution to NovelAI is documented through novelai uses a custom finetuned model with a recognizable rendering style, which strengthens the takedown notice and supports parallel legal action.
