# Channels & threads
> Lockdowns, slowmode, hiding, nuking, and thread management.
## Lockdowns
A lockdown removes send permissions from a role so nobody can talk. It's the first thing to reach for when something's going wrong in a channel.
```javascript This channel theme={null}
!lockdown
```
```javascript A specific one theme={null}
!lockdown #general spam wave
```
```javascript The whole server theme={null}
!lockdown all
```
```javascript Timed theme={null}
!lockdown until 2h
!lockdown all until 6pm
```
```javascript Unlock theme={null}
!unlockdown
!unlockdown all
```
Requires **Manage Roles**. Aliases: `lock`, `l` / `unlock`, `ul`, `uld`.
`lockdown all until 6pm` accepts natural language, and respects your [timezone](/utility/everyday#timezones) if you've set one.
### Which role gets locked
By default it's `@everyone`. If your server gates access behind a member role instead, point it at that:
```javascript theme={null}
!lockdown role @Member
```
### Channels to leave alone
```javascript theme={null}
!lockdown ignore #staff-chat
!lockdown ignore list
!lockdown ignore remove #staff-chat
!lockdown ignore clear
```
Ignored channels are skipped by `lockdown all`, which is how you keep staff coordination working while the rest of the server is frozen. Alias: `exempt`.
`unlockdown all` only unlocks channels **it** locked. Channels that were already private stay private, so you can't accidentally expose a staff channel by unlocking the server.
## Slowmode
```javascript Set it theme={null}
!slowmode #general 10s
```
```javascript Longer theme={null}
!slowmode #general 5m getting heated
```
```javascript Remove it theme={null}
!slowmode off #general
```
Requires **Manage Channels**. Aliases: `slow`, `slowmo`, `cooldown`, `cd`. Discord's maximum is 6 hours.
## Hiding and revealing
```javascript Hide from a member theme={null}
!hide #staff @someone
```
```javascript Hide from a role theme={null}
!hide #staff @Member
```
```javascript Reveal again theme={null}
!reveal #staff @someone
```
Requires **Manage Channels**. `hide` aliases: `private`, `priv`. `reveal` aliases: `unhide`, `public`.
With no target, it hides the channel from `@everyone`. This edits channel overwrites, so it's the same thing you'd do in channel settings — just faster.
## Topics
```javascript theme={null}
!topic #general read the pinned messages
!topic remove #general
```
Requires **Manage Channels**.
## Nuking a channel
```javascript theme={null}
!nuke
```
Clones the current channel — same name, permissions, position, topic — and deletes the original. Instant way to wipe a channel with no history limit.
Requires **Administrator**.
The new channel has a **new ID**. Anything referencing the old one breaks: pinned message links, webhooks, sticky message configs, counter channels, ticket panels. Re-point those afterwards.
### Scheduled nukes
```javascript theme={null}
!nuke add #daily-chat 1d
!nuke list
!nuke view #daily-chat
!nuke remove #daily-chat
!nuke clear
```
Wipes the channel on a repeating interval. Popular for daily-reset channels and temporary event channels. `nuke clear` needs **Manage Channels** and **Manage Messages**; the rest need **Administrator**.
## Threads
```javascript theme={null}
!thread lock
!thread close
!thread open
!thread rename bug reports
!thread delete
!thread unlock
```
Requires **Manage Threads**. Each takes an optional thread and reason — omit the thread to act on the one you're in. Aliases: `threads`, `t`.
| Command | Aliases | Effect |
| --------------- | --------------------- | ------------------------------ |
| `thread lock` | `l` | No new messages, stays visible |
| `thread unlock` | `ul` | Allow messages again |
| `thread close` | `archive` | Archive it |
| `thread open` | `unarchive`, `reopen` | Bring it back |
| `thread rename` | `name` | Rename |
| `thread delete` | — | Delete permanently |
### Preventing auto-archive
Discord archives inactive threads on a timer. To keep one alive indefinitely:
```javascript theme={null}
!thread add #important-thread
!thread list
!thread unwatch #important-thread
!thread clear
```
Requires **Manage Channels**. Watched threads are automatically unarchived whenever Discord archives them.
To create a thread on **every** message in a channel automatically, see [autothreads](/setup/channels#autothreads).
