If user has no shell access I suppose the problem is that the user might
be able to overwrite an existing file. The problem is what
owner/permissions/flags the files will have after transfer.
I don't know if this will work, but check if setting append only flag on
a directory might do. I would expect the append only flag on a directory
to allow only creating new files, so existing files cannot be overwritten.
Other flags might also be required, also check what you can do with ACL
and extended attributes.
