Yep. Had an ex-customer explicitly tell us he and his partner don't pay for anything. $8k later, we refunded them both because of an entirely unfounded rant and 1* reviews. They get away with it. Seconded on a system that tracks reviewers. You explicitly need to track their first review and their updated review - these people often update from a 1* to a 5* after a refund. Let us know: - Their average first rating - Their average total rating - How often a user changes from a 1* to a 5* / upgrades their review. This will point out abusers.
