Mistake 1: The Black Box Deception ❌
What happens: Users draw black rectangles over text without deleting content
Why it fails: Text remains extractable via copy/paste or PDF editors
The fix: Use "Content Removal" not annotation tools
Real-world disaster: A pharmaceutical company leaked clinical trial details this way, resulting in $1.2M GDPR fines.
Mistake 2: Metadata Blind Spots 🕵️♂️
The risk: Hidden document details exposing:
- Author names

- Geolocation data
Mistake 3: Layer Overload 🔍
PDFs contain multiple layers where text can hide:
- Comment layers
- Image alt text
- Embedded attachments
Mistake 4: "Secure" Tool Traps 🚫
Free PDF editors often:
- ☑️ Preserve original text in XFA forms
- ☑️ Fail to sanitize cross-references
- ☑️ Leave XML tags containing redacted text
Mistake 5: The Human Factor 👥
Common workflow errors:
- Forgetting to redact duplicate text
- Missing version control
