I use $ENV{USERNAME} because it works on Unix and on Windows, IME. $ENV{LOGNAME} is probably the oldest one on the Unix side and so may be the most widely supported. You can even use something like $ENV{LOGNAME} || $ENV{USERNAME} || $ENV{USER} (assuming you don't let anybody have a username of "0").

Of course, if you are worried about preventing people from pretending to be somebody else, then you shouldn't rely on an environment variable.
