No. Rostra deletion is signed metadata that asks compliant clients to stop showing the content and permits their locally stored bytes to be garbage collected when no longer referenced. It cannot force peers that already replicated the content—especially malicious or independently operated replicas—to erase their copies. Even locally, deletion makes bytes eligible for later garbage collection; it is not immediate secure erasure.
