You have to first check if the user who created the files has privs
such as SYSPRV ? It allows user to create files with either his/her
UIC or that of another UIC. Since it is possible also that the
intended directory could have RWED to group or world may allow
different users to write files into it. A common phenomenon in some
directories at our site (We also run EUNICE which as /tmp writable
and also /usr too...which as all too-corruptible bin files also )

A workble solution is to prevent group either W or D access to all
but their own and provide ACL controls to directories that need to
be shared by users from different groups ....
