# `widely_seen`: many other accounts checked the address inside a day

At least three other Spaw accounts looked the address up in the last 24 hours — an address hitting many signup forms at once.

- Weight: +20
- Dataset: lookup-velocity
- Read from: `widely_seen`
- Verdict reasons it comes with: none — a score-only signal

The count is kept as a keyed hash of the address with the account ids that saw it and when, for a day; the caller's own repeats never count, and nothing is held about who. Null means nobody could count: the guest demo, the sandbox, test addresses and invalid syntax.

It reads from widely_seen and comes with no verdict reason.

**What to do.** At signup, ask for a second factor or slow the flow: the address is being used by something automated rather than by one person.

```json
{
    "email": "mia@acme.com",
    "deliverable": "deliverable",
    "widely_seen": true,
    "risk_signals": [
        {
            "signal": "widely_seen",
            "weight": 20,
            "dataset": "lookup-velocity"
        }
    ]
}
```
