Remove AI training on me content from Signal

Why this happens on Signal

• Signal's zero metadata model is privacy protective for legitimate users but provides no platform side enforcement option for NCII victims. Content can be forwarded to other Signal users without trace.
• Character bot platforms allow users to upload reference images and intimate content to fine tune custom characters. These platforms have been documented hosting NCII fine tuned models against named individuals.
• Generative models can also be trained on individual's content for the purpose of producing unlimited synthetic intimate output. The training set itself is the underlying NCII even if the outputs are technically synthetic.
• Cross platform spread is the rule, not the exception. Content first appearing on Signal typically reaches between four and twelve additional platforms within 72 hours through reposts, mirrors, and screenshot redistribution.

The takedown process

What to do, step by step

1. 01
   Document every instance before reporting Capture full page screenshots with the URL bar visible, the posting account handle, and the upload timestamp. The platform hosting the model or chatbot
2. 02
   Run a biometric scan to find every copy across platforms Content first appearing on Signal 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 AI generated derivatives.
3. 03
   Dispatch the takedown notice to Signal Signal does not have content moderation tooling because of its end to end encryption and zero metadata architecture. Removal of content requires action against the sender directly.
4. 04
   Capture the AI tool fingerprint for the legal record Most AI generated NCII contains visible artifacts or watermarks indicating the specific tool used. Capture this evidence alongside the content itself. The AI tool operator may be a separate defendant in addition to the distributor.
5. 05
   Escalate through hosting and CDN if required Signal's architecture means there is no platform side enforcement. Action against the sender is the only available remedy. Police reports with the sender's phone number and law enforcement subpoenas are the practical path.
6. 06
   File a police report and preserve the legal record 47 USC 223a TAKE IT DOWN Act for both the training data and the synthetic outputs provides the federal basis for the takedown. Document every notice sent, every platform response, and every removal confirmation in a single evidence file. ScanErase produces this Verified Removal Package automatically as your case progresses.

Legal context

• Signal cannot be compelled to remove content because it does not have access to it. The TAKE IT DOWN Act enforcement against Signal is therefore ineffective. The remedy is action against the sender under state NCII statutes.
• 47 USC 223a TAKE IT DOWN Act for both the training data and the synthetic outputs
• Right of publicity claims for the unauthorized use of likeness in model training and inference
• Capture screenshots immediately and record the sender's phone number. Signal does not retain message metadata, so law enforcement subpoenas against Signal yield very little. Subpoenas against the sender's mobile carrier are more productive.
