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.

Of those 12, two are problems: claim_findings[0] (the Albanian seizure date is a year off, 2024-10 instead of 2025-10, contradicting the page's own text) and claim_findings[10] (the 464-victim claim rests on a dead RussSpain link), giving about 17% disputed or unverifiable. Separately, the Born2Invest citation is dead and used in five places (claim_findings[1] to [5]); the underlying CNMV and closure facts are corroborated by Genbeta, so this is a sourcing defect, not a false claim, and it pushes the penalty toward the upper end of the minor band.
