Multi-Join Protection detects the signature of a coordinated bot attack: a burst of new accounts joining with the same username or nickname. When it sees one, it bans the entire group automatically — no moderator needed.
Available to active Subscribers. It’s switched on automatically when you activate your subscription, so most servers never need to configure anything.

​
How It Works

  1. Hashbot tracks incoming joins and groups them by username and nickname (normalized, so trivial character tricks don’t split the group)
  2. When 5 or more members with the same name join within a few minutes of each other, all of them are banned
  3. Each ban appears in your ban logs with the reason Multi-join
Allowlisted members, Hashbot managers, administrators, and bots are never counted or banned by Multi-Join Protection.

Enabling and Disabling

Multi-Join Protection is enabled automatically when you run /subscription activate. To toggle it manually:
You can also toggle it from the Dashboard Settings page.

Looking for join-rate lockdown?

Multi-Join Protection targets same-name bot floods. If you want your server to lock down automatically when too many members join too fast — regardless of their names — that’s the Anti-Raid Auto-Trigger, a free feature configured on the Anti-Raid page.

Best Practices

  • Leave it enabled — the 5-same-name threshold is far above anything organic, so false triggers are extremely unlikely
  • Combine with Verification and Anti-Raid for layered protection: verification blocks individual bots, multi-join bans name-clone floods, and anti-raid lockdown stops high-volume raids
