General notes
- 01Black bars break the sentence. A model given [REDACTED] called [REDACTED] writes worse than one given Jane Doe called 555-0142.
- 02So swap in realistic decoys and swap back after the reply. The trick: decoys that can never belong to a real person. Standards bodies already reserved them.
