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
- 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. - 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.
- 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.

The alert states the Exchange 'is not registered as a broker-dealer or as a security exchange,' and was issued in response to a complaint filed with the agency's Securities Division.

The operators allegedly claimed investors could achieve 'up to 3x returns' by trading 'in unison' and 'sniping' trades using leverage of up to 75x. This recruitment-via-social-media, relationship-building, and promise-of-outsized-leveraged-returns pattern is consistent with what is commonly termed a 'pig-butchering' investment scam, though AVOID.NET notes this specific characterization is an inference from the alert's described tactics rather than a term used by DFI itself.","heading":"Alleged Recruitment and 'Pig-Butchering' Pattern","severity":"critical","sources":[{"credibility":1,"name":"Washington DFI: Alleged Cryptocurrency Trading Platforms Szvon-Ex.com Appears to Be Engaged in Fraud","type":"regulatory","url":"https://dfi.wa.gov/alerts/alleged-cryptocurrency-trading-platforms-szvon-excom-appears-be-engaged-fraud"}]},{"content":"The DFI alert states that when the investor sought to withdraw funds, he was told the withdrawal amount was 'too large' and that he would need to join a paid 'VIP Channel' to proceed. The investor was subsequently told he needed to pay an additional 'conversion fee.' The alert also describes 'Maguire' promising to return all investor funds and 'top up' the account if the investor 'recharged' the Exchange with an additional $10 million in non-Exchange funds to 'unfreeze' the account — a demand consistent with advance-fee recovery scam tactics layered on top of the original scheme.","heading":"Alleged Withdrawal Obstruction and Fee Extraction","severity":"critical","sources":[{"credibility":1,"name":"Washington DFI: Alleged Cryptocurrency Trading Platforms Szvon-Ex.com Appears to Be Engaged in Fraud","type":"regulatory","url":"https://dfi.wa.gov/alerts/alleged-cryptocurrency-trading-platforms-szvon-excom-appears-be-engaged-fraud"}]},{"content":"DFI's alert states that a single complaining investor lost 'over $870,000' between July 2025 and January 2026, made across 'more than 60 cryptocurrency transfers' to the Exchange. The alert further indicates the investor's platform-displayed account balance had purportedly grown to $4.6 million at the time withdrawal was attempted, a figure consistent with fabricated on-screen balances typical of this type of fraud rather than real, withdrawable funds. No other victims or aggregate loss totals across multiple investors have been independently verified in publicly available sources at this time.","heading":"Documented Victim Losses","severity":"critical","sources":[{"credibility":1,"name":"Washington DFI: Alleged Cryptocurrency Trading Platforms Szvon-Ex.com Appears to Be Engaged in Fraud","type":"regulatory","url":"https://dfi.wa.gov/alerts/alleged-cryptocurrency-trading-platforms-szvon-excom-appears-be-engaged-fraud"}]},{"content":"DFI explicitly states that the Exchange 'is not registered as a broker-dealer or as a security exchange.' AVOID.NET has not independently located any registration, license, or regulatory authorization for szvon-ex.com or szvon.com with any financial regulator, including the U.S. SEC, CFTC, FinCEN, or the UK Financial Conduct Authority. The absence of any verifiable licensing is a significant risk indicator consistent with the platform's alleged fraudulent conduct.","heading":"Registration and Licensing Status","severity":"high","sources":[{"credibility":1,"name":"Washington DFI: Alleged Cryptocurrency Trading Platforms Szvon-Ex.com Appears to Be Engaged in Fraud","type":"regulatory","url":"https://dfi.wa.gov/alerts/alleged-cryptocurrency-trading-platforms-szvon-excom-appears-be-engaged-fraud"}]},{"content":"Several independent scam-review and consumer-warning websites (e.g. TracingTheScams, TracingFrauds, ReviewTrustCenter, Scam-Detector) have separately published reviews characterizing szvon.com / szvon-ex.com as a likely scam or untrustworthy platform. These are low-credibility (Tier 3) sources of unclear editorial rigor, and their claims are not independently corroborated beyond general warnings about lack of licensing and scam-pattern characteristics already described in the DFI alert. They are noted here only as corroborating context and should not be treated as independently establishing additional facts.","heading":"Independent Scam-Review Coverage (Low Confidence)","severity":"low","sources":[{"credibility":3,"name":"Szvon Ex Review - Legit Investment or a Scam?
