This post is uploaded by someone completely annonymous.
Not even user_[num]. It's just blank.

I've been on a mad hunt going through old posts and looking at their edit history, and it seems like all posts between post #13 to post #20714 are just like that: totally blank initial tagger and uploader

the edit history doesn't start attributing an uploader until post #20715 which was attributed to user #6 (who when you look at their uploads; has uploaded post #88, but it just doesn't attribute them in the edits)
