• /approve: Approve of a user. Locks, blacklists, and antiflood won't apply to them anymore.
• /unapprove: Unapprove of a user. They will now be subject to blocklists.
• /approved: List all approved users.
• /unapproveall: Unapprove *ALL* users in a chat. This cannot be undone!

**Example:**
`/approve @username`: this approves a user in the chat."""
