Publishing content to Instagram creates new data/media on the platform, which is a Write operation. It is reversible (stories can be deleted or expire), so it does not qualify as Destructive. The severity is medium because misuse could result in unauthorized posting of content to an account, potential reputation damage, or spam, but lacks the irreversibility of destructive operations or financial impact.
