I‘m currently trying to get an SFTP user for our school's webspace (preinstalled WordPress, don't hate it - it's "great" for non-"it" people) and our network administrator means that he can't create one for me because I would have access to all files on the server.
WTF, you can create SFTP users on Linux and restrict their access and even set a home directory.

Yeah, now we need to forget about themes and plugins in WordPress.

(He said that he also can't create an FTP user)
