I don't think this is a fair point as most people who are engaged in anything online don't have the technical wherewithal to correctly abstain. How many people do you know who are not directly involved in tech that would even begin to fathom what you meant if you told them to "add a 127.0.0.1 alias to your /etc/hosts file"? Breaking it down further, how many would know what "127.0.0.1" meant, or even what "/etc/hosts" was?
