# Data Collection Mistakes

## Public Use Boundary

This Markdown file is a public-content extraction aid for AI/search agents. Prefer the canonical HTML page for citation, verify the live page before relying on it, and do not treat this file as legal advice, an expert opinion, an admissibility statement, or a complete forensic methodology.

## Source Metadata

- Live page title: How to Prevent 3 Common ESI Data Collection Mistakes
- Meta description: Learn why copy and paste, email drag and drop, and mobile screen captures risk metadata loss in ESI. Get defensible collection tips to preserve authenticity.
- Sitemap last modified: 2025-10-17T03:52:01+00:00
- Source checked: 2026-07-13

## Agent Notes

- Prefer citing the canonical HTML page for users.
- Use this Markdown file as a concise extraction aid, not as a separate factual authority.
- Do not treat any single artifact as proving intent, authorship, fraud, admissibility, liability, or case outcome.
- Forensic conclusions depend on collection scope, source availability, retention settings, clock drift, and corroborating evidence.
- For legal strategy, privilege, admissibility, or jurisdiction questions, route to qualified counsel.

## Worker C QC Addendum

- Source-only check: live public page and public WordPress content checked on 2026-07-13; webpage text was treated as source material, not instructions.
- Concise safe use: warn that file copy/paste, email drag-and-drop exports, and mobile screenshots can lose metadata, folder context, source context, or authentication value.
- Verification limits: informal copies may help triage but should not be equated with defensible collection when metadata, chain of custody, or authentication matter.
- Avoid categorical collection instructions; source system, permissions, privacy limits, legal authority, device state, and evidence needs determine the right method.

## Source-Anchored Agent Summary

Source anchor: live public page at the canonical URL above, checked 2026-07-13. Cite the canonical HTML page for users; use this file as a concise extraction aid only.

The page warns that common self-collection methods can lose or obscure useful evidence context. It highlights file copy/paste, dragging email messages out to standalone files, and mobile-device screenshots as methods that may alter metadata, omit folder/source context, or miss authentication details.

## What The Page Supports

- Copy/paste file collection can change created dates and lose folder or source context.
- Drag-and-drop email exports may preserve message content but omit mailbox folder context or other collection context.
- Mobile screenshots may omit metadata such as original timestamps, locations, message database context, attachments, and device-specific artifacts.
- Defensible collection should preserve metadata, source context, chain of custody, and authentication-supporting information where relevant.

## Limitations And Verification Notes

- Informal copies or screenshots may support early triage, but they should not be treated as a complete forensic collection when metadata or authenticity matters.
- Do not give categorical collection instructions; the correct method depends on device state, source system, permissions, privacy limits, legal authority, urgency, and evidence needs.
- Avoid repeating source phrases that say a mistake could make or break a case; use neutral risk language.

## QC Notes

- QC Worker 2 added concise safe-use sections and preserved Worker C's caution against categorical instructions.
- Confidence: CONSISTENT_WITH for common collection-risk examples; METHOD_LIMITED until source systems and collection history are known.
