2026 PixieSteed — alleged multi-billion-row China compilation bundle (forum; unverified scope)

Cybercrime forum posts attributed to a persona such as “PixieSteed” described a curated “mega-collection” on the order of tens of billions of rows and multi-terabyte scale, allegedly aggregating disparate Chinese e-commerce, logistics, and public-sector datasets (including brand names like Pinduoduo and major couriers in open-source chatter). No independent forensic validation or government acknowledgement was available in mainstream outlets at listing time; such bundles often mix recycled leaks, marketing hype, and partial dumps. This record exists to index the public narrative, not to assert a single synchronized breach of one organization.
