A common ploy for white hats and black hats was to try uucp remotesys!/etc/passwd ~/remotesys or the like, and see what came in and whether it had any easy hashes (shadow password files didn't quite exist yet). The system known to the uucp world as research! was more careful: / was mapped to /usr/spool/uucp. We left a phony etc/passwd file there, containing plausible-looking entries with hashes that, if cracked, spelled out why are you wasting your time I don't remember whether anyone ever stole it by uucp, though I think Bill Cheswick used it to set up the phony system environment for Berferd to play in (Google for `cheswick berferd' if you don't know the story).
