Online content can change without warning. Evidence should be collected promptly and with enough context for another reviewer to reconstruct what was observed.
Capture the source
Save the complete direct URL and stable identifiers such as post, listing, seller, or channel IDs. Record the platform, page title, date, time, and time zone. Note whether login, language, region, or device settings affected the page.
Preserve visible context
Screenshots should show the disputed material together with relevant account information, captions, pricing, timestamps, or surrounding page elements. For video, record the relevant timestamps and preserve a permitted copy where appropriate.
Keep originals separate
Retain downloaded files in their original form. Store annotations, crops, and comparisons as working copies rather than replacing the original. Consistent filenames, version labels, controlled storage, and hashes can support integrity.
Connect evidence to ownership
Link each reported item to the original work, source file, publication record, license history, and current owner. Separate factual observations from legal conclusions.
The level of formality required depends on the purpose of the case. Litigation, disputed ownership, or regulated evidence may require specialized collection and preservation guidance.
