# Raids, mass deletes, and anti-nuke

Join bursts, channel wipes and abused mod powers. Sift alerts you, and can lock the server down or undo the damage.

These features protect the server itself, not the messages in it.

## Raid alerts

When a lot of accounts join in a short window, Sift posts an alert listing the new accounts. With auto-lockdown on, it also closes text channels until you run /lockdown locked:false scope:server.

## Minimum account age

Optional, under /settings → Raid protection. Accounts younger than the age you pick are held behind the verify gate (or timed out) until they're old enough, or kicked with a DM saying when to come back. Each one is a case with a Let them in button.

## Dynamic slowmode

Optional, under /settings → Raid protection. When floods or a hot message rate hit a channel, Sift raises that channel's slowmode up to a cap you pick. Once chat calms down, it puts back whatever slowmode the channel had before.

## Anti-nuke

Rapid channel or role deletes, or a wave of bans, can make Sift strip dangerous permissions from whoever's doing it or time them out, even if they technically had permission. Allowlist your trusted mods and roles so real cleanup during a raid doesn't backfire.

## Rebuild

Stopping an attack is half the job. Rebuild puts the server back: deleted channels and categories come back with their permissions, deleted roles with their settings, bans get lifted and role permission changes are undone. Press Preview rebuild on the anti-nuke alert, or run /rebuild restore. You see exactly what it'll do before anything changes.

Staff roles, and up to 10 roles you pick with /rebuild roles, go back to everyone who had them. Messages in a deleted channel can't be brought back, because Discord doesn't keep them.

## Mass delete protection

Bulk message deletes by anyone who isn't the owner get treated as suspicious and logged for review.
