This is a site for original novels.
Tony allows translations to be hosted here because he also owns Scribblehub's sister site, Novelupdates, which exists specifically as a directory of translated novels.
Tony wanted a place to host original novels and he also wanted a place where translators could archive their works without fear of their site dying eventually if they didn't regularly pay for domain fees or whatever. Scribblehub was the answer to both issues, but it was still primarily aimed towards original works, so Tony hides all translations and lets them only be accessible through direct links.
