As a part of the Federal Trade Commission v. Microsoft lawsuit, technology company Sony had to produce several documents, one of which was a report—with confidential financial details redacted—sent by PlayStation chief Jim Ryan. Unfortunately, on June 28, things didn’t go according to plan.

The redactions were made in black Sharpie instead of using redaction tape, or redaction software, a more common method. The problem: When one scans a document, the Sharpie ink can occasionally lighten, making some redactions visible on the electronic document.
