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.

Verdict: over-penalized. Page content is treated as accurate; the trust_score band is miscalibrated. Coinbase is a legitimate, NASDAQ-listed, publicly traded company (COIN) and the largest U.S. cryptocurrency exchange by volume. Every major incident documented on the page is either a fully-resolved enforcement action (CFTC 2021, NYDFS 2023, SEC dismissed 2025), a security breach suffered by the entity at the hands of bribed contractors (May 2025 insider data theft), or losses inflicted on users by third-party social engineers impersonating Coinbase — none of these events constitute fraud by Coinbase itself. The WARNING band (20–49) is defined on this platform as 'elevated fraud/loss risk or unresolved severe incident'; the most material unresolved risk (the SEC lawsuit) was formally dismissed in February 2025, and the CFTC and NYDFS penalties are settled. What legitimately remains are: documented AML/KYC compliance failures, an ongoing pattern of user exposure to social-engineering scams (which Coinbase has been slow to mitigate), and the Base blockchain controversies (token pump-and-dump optics, OP Stack departure). These are material caveats for a real platform but place Coinbase squarely in the CAUTIONARY band (50–69). A score of 62 reflects that Coinbase is a legitimate operator with documented negligence-class compliance failures and an unresolved user-safety pattern, but no evidence of entity-level fraud, no active regulatory shutdown risk, and a clear public-company governance structure an outside skeptic can verify via SEC EDGAR filings.","score_delta":0,"sequence_num":4,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
