I've made a habit over the years to make a make a three step process out of it:
1. Keep the user, but lock their password
2. Rename the account to X-username, so the files still exist, but an
'ls -la' gives a nice reminder that the user is no longer with us.
This also prevents any errant crontabs from executing as this user
3. remove ~/.ssh - this shouldn't be necessary anymore, but it used to
be that some combinations of SSH server & OS would not check to see if
the password was locked, hence allowing logging by certificate
I vote for keeping the files and the user around. If someone has
interesting code or documentation, someone may want to refer to it
later. For instance, if someone wrote a blog post to his ~/public_html
directory on he solved a problem with some internal code, you don't
want it disappearing from your intranet search suddenly when they
leave. Same goes for his replacement wanting to nose around his
~/.profile for the environment variables he forgot to document. :)
