Verify a decision

Every moderation decision on AVOID.NET is anchored to the Solana blockchain. You don't have to trust us — you can verify cryptographically that we committed to a verdict at a specific moment and have not rewritten it.

How verification works

  1. We commit. When a moderator accepts/rejects a submission, we serialize the decision into deterministic UTF-8 bytes (payload_canonical_string), hash it with SHA-256, encode the digest as base58, and write it to Solana inside an SPL Memo v2 transaction.
  2. We store the bytes. The exact bytes we hashed are stored alongside the decision in our database. Anyone can read them and recompute the hash in any language.
  3. You compare three values. Database hash, your independently-recomputed hash, and the hash inside the on-chain memo. If all three match, the decision is authentic and timestamped.
The on-chain memo format is AVOID.NET|v1|h:<b58-sha256>|d:<id>|t:<iso>

Find a signature on any investigation page's decision log, or run python -m src.verify_decision --signature <sig> for a CLI check.

According to the DOJ, defendants \"managed, worked for, and recruited others to work at three different companies named Ko Thet Company, Sanduo Group, and Giant Company that allegedly operated several scam centers.\" In April 2026, two criminal complaints filed in the Southern District of California charged Wiliang Awang, Andreas Chandra, and a fugitive co-defendant — all alleged Indonesian nationals — along with Lisa Mariam, with wire fraud conspiracy and money laundering conspiracy tied to schemes run under the Sanduo Group and Giant Company names. Awang (age 23) was apprehended by Royal Thai Police and Chandra (age 29) was apprehended by Dubai Police; the case is tracked under docket number 26MJ2335-AHG. These are criminal allegations; the defendants have not been convicted and are presumed innocent unless proven guilty.","heading":"DOJ Criminal Charges Naming Sanduo Group","severity":"critical","sources":[{"credibility":1,"name":"DOJ Office of Public Affairs — Coordinated Takedown of Scam Centers Leads to at Least 276 Arrests","type":"regulatory","url":"https://www.justice.gov/opa/pr/coordinated-takedown-scam-centers-leads-least-276-arrests-alleged-managers-and-recruiters"},{"credibility":2,"name":"Hoodline — San Diego Feds Pounce After 276 Nabbed In Dubai Crypto Scam Bust","type":"news_article","url":"https://hoodline.com/2026/04/san-diego-feds-pounce-after-276-nabbed-in-dubai-crypto-scam-bust/"}]},{"content":"The DOJ and associated reporting describe the alleged scheme as a classic \"pig-butchering\" operation: scammers cultivate a victim's trust over time — often through simulated friendship or romance — before persuading the victim to move money and cryptocurrency into fake investment platforms secretly controlled by the scammers. Victims were shown fabricated profits and encouraged to contribute larger sums, in some cases financed through loans; once funds were transferred, victims lost control of the assets, which were then allegedly laundered through additional accounts. The charges carry a potential maximum sentence of up to 20 years in prison for wire fraud conspiracy and money laundering conspiracy. No public information reviewed identifies specific dollar losses attributable to Sanduo Group individually, as opposed to the broader multi-company operation.","heading":"Alleged Modus Operandi: Pig-Butchering Fraud","severity":"high","sources":[{"credibility":1,"name":"DOJ Office of Public Affairs — Coordinated Takedown of Scam Centers Leads to at Least 276 Arrests","type":"regulatory","url":"https://www.justice.gov/opa/pr/coordinated-takedown-scam-centers-leads-least-276-arrests-alleged-managers-and-recruiters"},{"credibility":2,"name":"Hoodline — San Diego Feds Pounce After 276 Nabbed In Dubai Crypto Scam Bust","type":"news_article","url":"https://hoodline.com/2026/04/san-diego-feds-pounce-after-276-nabbed-in-dubai-crypto-scam-bust/"}]},{"content":"Sanduo Group's alleged operations were part of a much larger coordinated crackdown involving the FBI, Dubai Police, and the Chinese Ministry of Public Security, along with Thai authorities. The overall operation resulted in at least 276 arrests, the dismantlement of at least nine scam centers, more than $701 million in cryptocurrency restrained by a U.S. government Scam Center Strike Force, an additional $33 million in funds identified as linked to investment fraud schemes globally, more than 120 phishing domains confiscated, and a cluster of 503 fake investment websites seized.

It is unclear whether \"Sanduo Group\" refers to a formally incorporated company, an internal name used within a scam compound, or a loosely organized criminal enterprise. No reports reviewed specify the physical location(s) of Sanduo Group's alleged scam center(s) (e.g., which country or region), nor do they quantify victim losses attributable to Sanduo Group specifically, separate from the co-named Ko Thet Company and Giant Company. This absence of independently verifiable operational detail should be weighed when assessing confidence in claims specific to Sanduo Group as opposed to the broader indicted network.","heading":"Unverified and Unknown Aspects","severity":"medium","sources":[{"credibility":1,"name":"DOJ Office of Public Affairs — Coordinated Takedown of Scam Centers Leads to at Least 276 Arrests","type":"regulatory","url":"https://www.justice.gov/opa/pr/coordinated-takedown-scam-centers-leads-least-276-arrests-alleged-managers-and-recruiters"}]}],"sources_used":[{"credibility":1,"name":"DOJ Office of Public Affairs — Coordinated Takedown of Scam Centers Leads to at Least 276 Arrests; Alleged Managers and Recruiters Charged in San Diego","type":"regulatory","url":"https://www.justice.gov/opa/pr/coordinated-takedown-scam-centers-leads-least-276-arrests-alleged-managers-and-recruiters"},{"credibility":2,"name":"Hoodline — San Diego Feds Pounce After 276 Nabbed In Dubai Crypto Scam Bust","type":"news_article","url":"https://hoodline.com/2026/04/san-diego-feds-pounce-after-276-nabbed-in-dubai-crypto-scam-bust/"},{"credibility":2,"name":"The Hacker News — Global Crackdown Arrests 276, Shuts 9 Crypto Scam Centers, Seizes $701M","type":"news_article","url":"https://thehackernews.com/2026/05/global-crackdown-arrests-276-shuts-9.html"},{"credibility":1,"name":"FBI San Diego Field Office — Coordinated Takedown of Scam Centers Leads to at Least 276 Arrests","type":"official","url":"https://www.fbi.gov/contact-us/field-offices/sandiego/news/coordinated-takedown-of-scam-centers-leads-to-at-least-276-arrests-alleged-managers-and-recruiters-charged-in-san-diego"}],"summary":"Sanduo Group is named by the U.S. Department of Justice as one of three alleged criminal organizations — alongside Ko Thet Company and Giant Company — that operated cryptocurrency \"pig-butchering\" scam centers targeting American victims.
