Audit log

Every state-changing event for Pincoin: 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 page's core narrative (Modern Tech's MLM structure, the 40-48% return promises, the April 2018 collapse and investor protests, and the eight named founders) is corroborated across multiple independent 2018-era sources. However, the page contains several internal date contradictions (the cash-to-token switch is dated both January and April 2018 in different parts of the page; the Modern Tech founding/ICO-start timeline conflicts with corporate records showing the company existed only from October 2017 to March 2018), one clear overstatement contradicted by its own cited source ('hundreds' vs. the source's 'dozens' of protesters), a governmental-directive date off by a week with two distinct official actions conflated into one, and no coverage at all of what happened after April 2018 -- whether anyone was ever charged or the case was closed. The headline $660 million / 32,000-investor figures, while ubiquitous, trace only to victim/protester claims relayed by local media and were never confirmed by any documented police, court, or regulatory finding in the sources reviewed.

   The review disputes or leaves unverifiable 6 of 18 claims (33%), which falls in the 30-60% band that this platform treats as significant. The core narrative -- Modern Tech's MLM structure, the 40-48% return promises, recruitment commissions, the April 2018 investor protest, and the identification of eight named founders -- remains corroborated by independent contemporaneous sources (claim_findings[3], [4], [15], [16]). However, the page contains multiple internal contradictions: it dates the cash-to-iFan-token switch to both January and April 2018 in different sections (claim_findings[5], [11]); its opening timeline date and founding-date framing conflict with Vietnamese corporate records showing Modern Tech JSC existed for roughly four months, not the year-plus the page implies (claim_findings[9], [10]); it states the April 2018 protest involved 'hundreds' of people when its own cited Vice article says 'dozens' (claim_findings[14]); and it misdates a key government directive by a week while merging two distinct official actions into one (claim_findings[13]). Two coverage gaps rated high priority go to the page's foundations: the headline $660 million and 32,000-investor figures trace only to victim and protester claims relayed by local media and were never confirmed by police, a court, or a regulator, and the page never discloses this; and the page's account simply stops in April 2018 with no mention that no charges, prosecution, or case closure was ever found through 2026. A named individual's documented account of a more limited role is also omitted. The reviewer's moderate confidence (0.75) and the fact that the disputed items are largely dating and scale errors rather than a refutation of the central allegation keep the penalty toward the lower half of this band rather than the top.
