Agreed.

Well, I know pathetically little C -- basically, enough to write "Hello, 
World!" -- but then again, that's enough to write a program the prints out 
"Your account has been suspended." You could write two or three canned 
messages like this, each in a different executable, and name them 
"suspended-for-spamming", "suspended-for-cracking", and whatever else was 
appropriate, and have each one be a potential login shell.

(Probably the "real C programmer" way to do it would be to have just one 
script, with a variety of canned messages, that checked what name it had 
been invoked under and displayed the appropriate message. Then make all 
those names be symlinks to the one script. But I have no clue how to do 
that in C.)
