Member Events - Criminal

Event	Criminal’s response
Member joins	Welcome message (if a channel is set), `autorole` if configured
Member leaves or is kicked	Goodbye message (if set)
Member boosts	Boost message and a log entry
Member banned or unbanned	Log entry, moderation case where applicable
Roles, nickname, timeout change	Log entry with who changed it

Join

Both actions are independent:

/config channel welcome-channel #welcome
/config role autorole @Member

A failed autorole (role above the bot, missing permission) logs a debug line and doesn’t block the welcome message.

Leave

The goodbye message only fires on a member removal. Bans are reported through moderation and logs instead, because a banned member’s exit has its own case entry.

Boost

Detection is premium_since changing from empty to set, so a boost posted once won’t repeat on every reconnect. Boost messages are configured separately from booster roles.

Logging

Every event on this page also writes to the log channel when one is configured, including who made the change where Discord exposes it. See Server logs.
