PDF Redaction for Blind Review

Redact identifying information from academic papers for blind review.

CRITICAL RULES

1. PRESERVE References section - Self-citations MUST remain intact
2. ONLY redact specific text matches - Never redact entire pages/regions
3. VERIFY output - Check that 80%+ of original text remains

Common Pitfalls to AVOID

# ❌ WRONG - This removes ALL text from the page:
for block in page.get_text("blocks"):
    page.add_redact_annot(fitz.Rect(block[:4]))

# ❌ WRONG - Drawing rectangles over text:
page.draw_rect(fitz.Rect(0, 0, 600, 100), fill=(0,0,0))
