Records Tampering Detection

Digital forensics investigation documenting potential archive manipulation, backdated content, and unauthorized alterations to public records using Common Crawl verification.

Methodology: All findings ignore claimed dates, revision notes, and page metadata. Common Crawl serves as the immutable timestamp source. Unlike Wayback Machine, Common Crawl archives cannot be manipulated through takedown requests or retroactive edits - making it the authoritative source for detecting stealth modifications.

Critical Principle: When Wayback Machine and Common Crawl disagree, Common Crawl is authoritative. Wayback can be manipulated via takedown requests, user submissions, and retroactive edits. Common Crawl is a passive crawler with immutable archives beyond user control. All verification links above query Common Crawl's public index API - click to independently confirm findings.
