- When you terminate a user's account from the system, their UID may still own files. When you create new account, the system assigns it the next available UID, which is usually that of a terminated account. Thus the new account assumes ownership of all files that the old user owns, and gives the appearance that the user is already over quota though, even though nothing has been uploaded.
- Tarballs ( .tgz, .tar, .tar.gz) may have files that the user who tarred them up on a separate system owns. When you untar files on your server, they are assigned ownership of whatever account has that UID.
