What is covered in Fake Seller Reviews Detection?

Spot fabricated seller reviews. Pattern detection, verification, and platform safeguards.

How does Jurassic Depot help buyers avoid fossil fraud?

Listings require provenance and restoration disclosure. Buyers can request document review, use expert services, and rely on buyer protection for material misrepresentation.

Should I buy fossils without paperwork?

No. Missing locality, land type, or chain-of-custody documents is a major risk for illegal material, fakes, and failed disputes.

Fake Seller Reviews

Fake reviews inflate seller reputation. 50 fake 5-star reviews + zero real transactions = setup for large-scale fraud.

Red Flags

— All reviews within short timeframe

— All 5-star, no variation

— Reviewers have no other activity

— Generic text: 'Great seller, A+++'

— Multiple reviews from same day/IP

— 50+ reviews but 0 verified transactions

— Reviews mention items not in seller history

— Reviewers only post reviews — no bids, no purchases

— Identical phrases across different reviewers

— Burst of reviews after negative review

Detection Systems

Verified Purchase Flag

Only reviews linked to completed orders shown as verified. Unverified weighted lower.

Account Age Check

Reviewers must have account >7 days old. New accounts posting reviews flagged.

IP/Device Clustering

Multiple reviewers from same IP or device → all flagged as coordinated.

Pattern Detection

Burst of 5-star reviews from accounts with no purchase history = auto-flag.

Text Similarity

Systems check duplicate phrases across reviews. Identical wording = fabricated.

Cross-Reference

Review claims vs transaction data. 'Bought trilobite' but no trilobite sales = fake.

Platform Response

— Verified purchase badge separates real from unverified

— Fake reviews removed → trust score reflects genuine only

— Review manipulation = seller suspension

— Sellers cannot delete negative reviews

— Buyers can flag suspicious reviews
