Firms, therefore, have a strong incentive to manipulate ratings using fake reviews. This presents a problem that academic researchers have tried to solve over two decades and on which platforms expend a large amount of resources. Nevertheless, the prevalence of fake reviews is arguably higher than ever. To combat this, we collect a dataset of reviews for thousands of Amazon products and develop a general and highly accurate method ","authors_text":"Ali Tosyali, Brett Hollenbeck, Davide Proserpio, Gijs Overgoor, Sherry He","cross_cats":["econ.GN","physics.soc-ph","q-fin.EC"],"headline":"","license":"http://creativecommons.org/publicdomain/zero/1.0/","primary_cat":"cs.SI","submitted_at":"2024-10-23T02:09:40Z","title":"Detecting fake review buyers using network structure: Direct evidence from Amazon"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2410.17507","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:c0c8ae31a364c796f29eb5df0cbc7772be6de2e15aeff21b2e7cb8282e5a2cfd","target":"record","created_at":"2026-07-05T09:24:23Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"fdcbeaaa0c86eef48e1394f13526a53339ee5ff1e68ee2151e98c8d6ba906af4","cross_cats_sorted":["econ.GN","physics.soc-ph","q-fin.EC"],"license":"http://creativecommons.org/publicdomain/zero/1.0/","primary_cat":"cs.SI","submitted_at":"2024-10-23T02:09:40Z","title_canon_sha256":"b7855269f8acc6c7c8ab43b720db6e3ba236da2416c8f4bf1a990ff1a35749c1"},"schema_version":"1.0","source":{"id":"2410.17507","kind":"arxiv","version":1}},"canonical_sha256":"8ba3c7e7b16aed7f75b0a4ae4b6f4392de7bbcdeed51897e4ca9572739b4b64e","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"8ba3c7e7b16aed7f75b0a4ae4b6f4392de7bbcdeed51897e4ca9572739b4b64e","first_computed_at":"2026-07-05T09:24:23.596209Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T09:24:23.596209Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"F6P4mROwlorOC9ZBY2AV0zI5JDUoTqng9Q0GZtHnjDjwcqrNRNS58NlJSftGeubIReNmXuneWYNC7pHHY2emAQ==","signature_status":"signed_v1","signed_at":"2026-07-05T09:24:23.596680Z","signed_message":"canonical_sha256_bytes"},"source_id":"2410.17507","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:c0c8ae31a364c796f29eb5df0cbc7772be6de2e15aeff21b2e7cb8282e5a2cfd","sha256:7184873b2f12b72ce111f3f145cfba41cc028993f98967075b4a5103fa049df1"],"state_sha256":"45601ffd8ae165b0bf432bb0ea557824523c8ad47fb8178b9d2a5fc513c81bde"}
