Default permission tier: 5
Deletes a number of messages. Literally just reprocesses your message as iab!del c <num>.
Logs are saved, and their ID is written to the Log Channel. Use iab!log to recover these logs (but currently not their attachments). The logs include information about who sent messages, what they sent, and all attachments. This is to allow administrator audits of purge operations.
num: Optional integer 0-6 that represents the state to send. If unspecified, a random value is used.
