Note that the Minitel itself had many backdoors (not all of them being blocked by servers) and has not been safe for years; the issue is somehow comparable: The {app|minitel} has built-in vulnerabilities {crummy code|hidden control codes}. Those of us that participated in the early days of it still remember that when you wanted to get rid of someone in a chat room all you had to do was to private a message containing <esc>:f<ctrl-c><esc>9g Michel.
