# Multi-Join Protection

> Configure the join rate threshold that automatically triggers Anti-Raid lockdown.

Multi-Join Protection monitors your server's join rate and automatically activates [Anti-Raid lockdown](/anti-raid) when too many members join in a short time window. This stops coordinated raid attacks without requiring a moderator to be online.

<Check>
  Free for all servers. Configurable thresholds let you tune sensitivity to match your server's normal join traffic.

### How It Works

Hashbot tracks every new member join with a timestamp. When the number of joins within a configurable time window exceeds your threshold, lockdown is automatically activated.

For example, with the default settings, if **20 members join within 10 seconds**, Hashbot immediately:

1. Activates Anti-Raid lockdown using your default action (Kick or Ban)
2. Blocks all subsequent joins for the configured lockdown duration
3. Logs the auto-trigger event to your log channel
4. Allowlisted members and Hashbot managers still pass through

### Configuring Multi-Join Protection

#### From the Dashboard

Go to the **Anti-Raid** page and configure the **Auto-Trigger** section:

| Setting               | Default    | Range            | Description                                |
| --------------------- | ---------- | ---------------- | ------------------------------------------ |
| **Enabled**           | Off        | —                | Toggle auto-trigger on or off              |
| **Join threshold**    | 20         | 3 – 100          | Number of joins that triggers lockdown     |
| **Time window**       | 10 seconds | 5s – 5 minutes   | How fast the joins must happen             |
| **Lockdown duration** | 1 hour     | 1 min – 24 hours | How long the auto-triggered lockdown lasts |

#### From Discord

```
/settings multi-join threshold:<number>
```

### Why Enable It?

* **Automatic response** — stops raids even when no moderators are online
* **Configurable sensitivity** — tune the threshold to avoid false triggers during legitimate growth spikes
* **Works with Anti-Raid** — uses the same lockdown system, so all your lockdown settings (action, exemptions, logging) apply automatically

### Best Practices

* Set the threshold **above** your server's normal peak join rate to avoid false triggers
* Start with a higher threshold (e.g., 20 joins in 10 seconds) and lower it if raids slip through
* Combine with [Verification](/verification) for layered protection — verification blocks bots individually, while multi-join protection stops mass raids

<Tip>
  To check if multi-join protection is enabled and review your current thresholds, visit the **Anti-Raid** page on the [Dashboard](https://dashboard.hashbot.com) or run `/settings status`.
