However, this can be bypassed by the `-P` option of `put` command. We are developing a shared hosting platform, therefore we definitely don’t want our users being able to upload any executable files.

Mount the filesystem in question with 'noexec', you probably also want 'nosuid' and 'nodev' anyways.
