What is feedback extortion in marketplaces?

Feedback extortion is user behavior where a user makes a good review conditional on exorbitant demands or threatens to give a positive review only in exchange for one.

On many marketplaces, a good rating means access to further customers or services, which can lead to good feedback being used as leverage. For example, on ride-hailing apps, providers that go under a certain rating will be banned from the platform. Good reviews can be integral to their livelihood. For customers, a low rating can mean no longer having access to services through the platform, as providers will not accept your requests.

Most marketplaces prohibit feedback extortion and use a double-blind review process to enforce the rule. However, feedback extortion still remains a problem on marketplaces.
