​
Overview

Unlike standard name filters or regex patterns, Multi-Join Protection detects clusters of users who join your server with similar usernames in a short time window. It functions as a specialized anti-raid system focused on impersonation patterns.

​
How It Works

When multiple new members join within minutes of each other — and their usernames resemble one another — Hashbot flags the group and takes action based on your configured punishment (ban, timeout, or delete).

​
Example

These names would trigger detection if joined in quick succession:
  • OpenSeaMint
  • OpenSea_mint
  • 0penSea_m1nt
  • 0penSeaM1nt
Hashbot recognizes patterns, even if none of these match your existing blocklist directly.

​
Why Enable It?

  • Automatically stops spoofing-based raids
  • No need to define every scam variant manually
  • Focuses on behavior and timing, not just names

​
Recommendation

We recommend enabling Multi-Join Protection on all servers — especially those vulnerable to coordinated impersonation attacks. To confirm whether it’s active or to adjust settings, run: /settings status
