There is a much more fine-grained ACL system in Linux which sits on top
of the standard file permissions. Have a look at, for instance,

 https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Storage_Administration_Guide/ch-acls.html

or 'man acl'

With this you will be able to give specific users different access
permissions on the files created.

As someone else said, ProFTPD also has a finer-grained permission
system - you can change access according to which user is logged in via
FTP and you can change which commands they have access to. In other
words you allow Alice access to a subset of commands which allow her to
upload files and create directories but not rename them.
