Review blackmail: what to do when a customer threatens a one-star

“Refund me or I'll leave a one-star review.” It arrives more often in hospitality and trades than anywhere else, and how you answer in the next ten minutes decides whether you have a case.

Preserve everything, immediately

Screenshot the message with the sender visible. Export the email thread. Keep the WhatsApp chat — do not delete the conversation after the dispute ends, which is the mistake almost everyone makes. Platforms recognise extortion, but only on evidence.

Do not concede in writing

A refund given “to make it go away” is often read later as confirmation that the complaint was legitimate. If a refund is genuinely warranted, give it on its own merits and say so in those terms — separately from any mention of the review.

What to reply

Short, factual, no threat of your own: acknowledge the complaint, state what you are willing to do and why, and stop. Never write anything you would not want a moderator to read, because a moderator may well read it.

Where it is reportable

• Tripadvisor has a dedicated process for blackmail attempts and takes the correspondence seriously.
• Google treats it under conflict of interest and prohibited content, depending on what the review itself says.
• Trustpilot will look at whether the described experience happened at all, which is often the faster route.

If the review lands anyway

File with the correspondence attached and the timeline laid out: date of service, date of demand, date of review. That sequence is what makes the case obvious to a reviewer who has thirty seconds to decide.

The longer-term fix

Staff need a script. Most blackmail attempts are made to a front-line employee who has no idea what to say and improvises a concession. A one-paragraph policy — acknowledge, escalate, never promise — removes the improvisation.
