"Deleting" a system user is frequently *not* what you want to do.
Your best bet is to make the user inactive.
passwd -l
...prevents logins on the account.
Change the user shell to /bin/false to prevent the user from running a
shell.
Checking under /var/spool will show crontabs and at jobs. Not sure if
there's a way to disable these, or if the 'passwd -l' trick does that.
Finally, the user is likely to have files on the system -- certainly
under /home (or $HOME, if not under /home), and possibly elsewhere.
It's the residual files which are th epirmary reason *not* to blindly
delete a user's /etc/passwd entry. Given a disabled account, the user
*cannot* log into the system. However the system administrator *can*
still identify files owned by that user, and move, change ownership, or
delete these as necessary.
Peace.
