Audit log

Every state-changing event for Poloniex: moderation decisions on community submissions, plus corrections and updates from the news pipeline. URL-based decisions are designed to carry three independent witnesses — the original source, an Internet Archive snapshot, and a Solana memo signed by our publicly-disclosed publisher key. Archive coverage is still being backfilled, so each decision below reports its own snapshot status rather than assuming one exists.

   The core facts hold: the SEC settlement ($10,388,309, August 2021), the OFAC settlement ($7,591,630, 65,942 violations), and the November 2023 hack date and headline loss. Two errors are disputed. The base penalty is $99,237,000, not $98.8M, and the 'no business operations and no employees' quote comes from OFAC's release, not the SEC order. The page also blends the platform period with the violation period, which OFAC dates July 2015 to September 2019. Several hack-detail and attribution claims were not independently checked, and the timeline entries carry no sources.

   Score: 58 → 58 (no score change)
   Of 10 claims reviewed, 2 were disputed and 3 could not be verified, giving 50%, which falls in the significant-issues band. The disputed items are claim_findings[0], where OFAC's own release gives a base penalty of $99,237,000 rather than $98.8 million, and claim_findings[1], where a quote attributed to the SEC order comes from OFAC's release. The unverified items (claim_findings[5], [8], [9]) were not checked rather than contradicted, and the core SEC and OFAC settlement amounts and the November 2023 hack were confirmed. Because reviewer confidence is low (0.5) and the errors are factual details rather than core allegations, the penalty is set at the lighter end of the band.
