Banned on Tuesday. Back on Wednesday with a new spelling.

Repeat offenders re-register with the same name, adjusted just enough to slip exact-match blocklists. Generative tools now produce the documents to go with it.

Where the check runs

At signup, against everyone you've already banned.

Every new account gets compared to the blocklist: past fraudsters, chargeback abusers, banned sellers. The attacker controls the spelling. The defense has to be spelling-proof.

Today

Blocklists that trust spelling.

  • Exact match means Katherine O'Brien and Kathryn OBrien are strangers.
  • Fuzzy rules tuned tight miss; tuned loose they flag your best customers.
  • Cross-script re-registration isn't even in the threat model.
  • Manual review queues grow linearly with signups.
With Onoma

A blocklist that survives respelling.

  • Score every signup against the blocklist; drift doesn't break the link.
  • Calibrated bands: auto-block, auto-clear, review the middle.
  • Works on names your rules have never seen, in any script.
  • Batch endpoint retro-screens the existing user base.
In the flow

Catch the re-registration at the door.

  • Signup-time scoring against the full blocklist.
  • Spelling-drift resistant: diacritics, initials, reordering, script hops.
  • Thresholds you can automate without a data-science project.
  • Evidence output for the trust & safety case file.
