From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Not sure if that one is still around but I know one person who ran a script with "deluser $USER" and it ate root resulting in fun messages like that
My local
deluserchecks if the user has any active process. I tried deleting all of the data by hand, but the process is still assigned to a user name and id.I'm not sure if this one can error still can be replicated.
Well you could manually edit /etc/password and shadow I suppose
I think I'll just take your word for it.
Easy to try in a virtual machine with snapshot. Or use a filesystem snapshot
