# SDK Types: Spam

## `SpamFields`

*Interface*

Hidden anti-spam fields auto-injected into form and review submissions.
The Lynkow API's `spamProtection` middleware verifies both values server
side; submissions that fail either check are rejected with a generic
200 OK so bots cannot probe the heuristic.

| Property | Type | Optional | Description |
| --- | --- | --- | --- |
| `_hp` | `string` | No | Honeypot field. MUST be left empty by real users; rendered as a hidden<br>input so genuine browsers ignore it but naive scrapers fill it in. |
| `_ts` | `number` | No | Client-side session start time as Unix milliseconds since epoch<br>(the return value of `Date.now()`). The server rejects submissions<br>whose `(now - _ts)` is below the minimum fill-in threshold (bots) or<br>above the maximum session lifetime (stale). |
