Preserve the review with the complete URL, profile name, date, time and visible platform context. Save screenshots showing the rating, heading, text and any replies together. Keep the original file and an unchanged PDF or web version. A copied sentence often no longer shows where or when it was originally published.
Connect the review with the specific stay. The booking confirmation, invoice, room number, messages, complaint and hotel response may show which event is being described. If the author’s status as a guest is disputed, that question requires its own records. Assumptions about identity or motives are not evidence.
Record every later change, including edits, deletion, new replies, platform reports and contact attempts. A short chronology with date, sender, statement and response prevents the original text from being confused with a later version.
