Step by step

Raid detection

A raid starts when more than joins members arrive within window seconds (default 10 in 30 s). Each joining account gets a risk score 0–100 from account age, default avatar, name patterns and whether the invite was created moments ago. Accounts above the high threshold receive the raid action; medium-risk ones are flagged in the alert.

!antiraid enable
!antiraid threshold 10 30
!antiraid action quarantine lock_on_raid:true       timeout / kick / ban / quarantine / alert only
!antiraid risk medium:40 high:70 min_account_days:7
!antiraid status

Lock on raid locks the server for the configured duration (10 minutes by default) and posts a staff alert; !unlockall ends it early. During a raid the temporary-voice creator channels can be paused too (Temporary voice → Pause during lockdown).

Join gate rules

Rule	Trigger	Value
`noAvatar`	Account uses the default avatar	—
`accountAge`	Account younger than N days	days
`unauthorizedBots`	A bot was added by someone who is not whitelisted for joingate (or all)	—
`inviteInName`	discord.gg / invite link in the username or display name	—
`usernamePattern`	Username matches a regular expression	regex

!antiraid joingate accountAge on quarantine value:7
!antiraid joingate unauthorizedBots on kick
!antiraid joingate usernamePattern on timeout value:"(?i)nitro|free\s*gift"

Actions for join gate: none, timeout, kick, ban, quarantine. To allow a specific person to add bots: !whitelist add user @them joingate. To allow a specific bot: !whitelist add bot <bot id> joingate.

Good to know

Medium must stay below high.
Lock on raid also locks out real newcomers; cohorts contain without locking, which is usually what you want.

If it does not work

Real people got quarantined during a shout-out. Check !raid cohorts: a genuine influx should be judged "surge"; if not, raise the join limit or turn lock_on_raid off.
