The photo section of Subway's official corporate page is currently being overwhelmed with pornographic Hentai images featuring the classic Subway footlong sandwich in lieu of a censorship bar.

The Daily Dot's Lauren Rae Orsini traced the prank back to a Facebook page dedicated to digital Japanese pop star Hatsune Miku.

Members of Hatsune Miku Troll had apparently been engaging in this odd hobby for some time, and were encouraged by the fan page's admin to post their creations directly to Subway's page.

The Dot links to this FacePunch thread containing "extremely specific Subway-themed hentai" as a source for many of the images.

Despite Subway's best efforts, the trolls refuse to allow the company to remove the offending photos. "[S]o subway removed my post and a couple others. brb posting more," wrote Yichao Ravioli, one of the more active trolls.

UPDATE: Subway has issued the following statement concerning the pornjacking of their Facebook page:

We are aware of the excessive spam on our Facebook wall and have removed all content that is in direct violation of our House Rules. We are in contact with Facebook to investigate the matter further and enact a swift resolution.
