Key findings

  • IPSecure connected ten nominally independent seller accounts by examining marketplace behavior alongside public business records.
  • Looking across accounts can reveal relationships that an investigation of one listing may miss.
  • Connections are investigative leads: a shared address alone does not establish misconduct or common ownership.

Investigating the network behind an offer

An individual seller profile provides only part of the picture. This case study brings together marketplace observations and business records to examine whether apparently separate accounts warrant a coordinated investigation.

For brand protection teams, the practical lesson is to investigate relationships as well as individual offers. Document the evidence supporting each connection, distinguish observations from inferences, and use further investigation to test the explanation.

The full whitepaper presents the case behind these findings. This is a case study, not an estimate of how common connected seller networks are across a marketplace.
