Report to the FBI Internet Crime Complaint Center (Stable Diffusion content on 4chan)

Why this matters for Stable Diffusion content on 4chan

• 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.
• 4chan boards including /b/ and /soc/ have historically been primary distribution points for NCII. Threads expire quickly but content is preserved in third party archives that mirror entire boards.
• Stable Diffusion content distributed through 4chan typically reaches between four and twelve additional platforms within 72 hours through reposts, mirrors, and cross platform redistribution.
• Source attribution to Stable Diffusion is critical for report to FBI because it establishes the AI generated nature of the content, which strengthens statutory claims under 47 USC 223a regardless of whether the depicted person ever existed in unaltered form.

How AI generator removal works

What to do, step by step

1. 01
   Preserve evidence before any other action Capture full page screenshots with the URL bar visible, save the highest resolution copy of the content available, and document the Stable Diffusion fingerprint indicators including stable diffusion outputs across versions have known visual fingerprints including characteristic noise patterns in flat regions and recognizable hand and finger artifacts. Full evidence package from the platform takedown including URLs and screenshots
2. 02
   Run a biometric scan to find every copy across platforms Stable Diffusion content distributed on 4chan rarely stays there. ScanErase indexes 2.4 billion face embeddings across 200 plus platforms and identifies every current hosting location in a single scan, including additional Stable Diffusion variations.
3. 03
   File the IC3 complaint with full evidence File at ic3.gov with the complete evidence package. The complaint should specifically cite the Stable Diffusion attribution and the 4chan distribution. Reference the United Kingdom (Stability AI) jurisdiction of the source service to support investigation routing.
4. 04
   Document the Stable Diffusion source attribution Stable Diffusion outputs across versions have known visual fingerprints including characteristic noise patterns in flat regions and recognizable hand and finger artifacts. This attribution evidence is critical for the legal record and supports stronger statutory claims regardless of which specific action you pursue.
5. 05
   Coordinate with 4chan platform removal 4chan threads expire automatically. Active removal requires emailing dmca@4chan.org with the thread URL. Archive sites such as warosu and archive.4plebs require separate filings.
6. 06
   File the complete evidence record for the legal track 47 USC 223a as the underlying federal NCII statute provides the foundational legal basis for this action. Document every notice sent, every platform response, and every confirmation in a single evidence file. ScanErase produces this Verified Removal Package automatically as your case progresses.

Legal context

• 47 USC 223a as the underlying federal NCII statute
• 18 USC 875 for interstate threat communications when sextortion is involved
• 4chan is below the covered platform threshold but is subject to DMCA and to state NCII statutes. The most effective leverage is the third party archive operators, who are typically more responsive than 4chan itself.
• Stable Diffusion attribution: The base model is open source and beyond removal action. Action proceeds against the specific fine tune model, the LoRA adapter that enables targeted generation, and the platform that hosts and distributes the harmful adapter.
