The command instead began broadcasting Hubbard's message to every machine on the internet and was stopped after Hubbard realised the message was being broadcast remotely after he received complaints from people at Purdue University and University of Texas. Even though the command was terminated, it resulted in Hubbard receiving 743 messages and complaints, including one from the Inspector General of ARPAnet.
