This made spoofing exponentially harder, as an attacker would need to reverse the hash or intercept the nonce in real-time—a non-trivial task on 2001 hardware. Consequently, IS3 became the first line of defense against "spoofed ops" (fake operator status), preserving the integrity of the chat ecosystem.
