Yeah, email aliases are easy to setup and low risk (although I recently 
had to kick my father from codewiz.org because his Mac was sending spam 
and hurting the reputation of my domain to the point I could no longer 
deliver to Gmail users :-)

The system-userdel script keeps around the home, so it's easy to 
re-instate them if they come back.

When the ldap password expires, they also cannot login via ssh with a 
key, because pam denies users with expired passwords.

Thomas has an interest in building and distributing system images for 
Sugar in various formats.

Probably, he can't easily another place to distribute such huge files, 
so I granted him extra filesystem quota when needed and asked him to 
delete old images that are no longer required.

I don't remember if we excluded his public_html/ from backups... maybe?

Thomas, your work is appreciated, but (as James also said) old OS images 
may may put users at risk. If we want to continue distributing them, we 
should also deliver security updates.

We don't want Sugar users to become spambots like my father's Mac :-)
