This refers to the 4chan meme of Anonymous, usually depicted with a blank green face marked "?" or "No Picture Available". Far more common on Danbooru is the relatively similar 2ch concept of the sin sack, though Anonymous is considered a representation of all 4chan users, while the sin sack tends to represent only the more fanatical otaku on 2ch.
