My bad for approving it b/c it was in the queue before yours. I was considering flagging it, but it seemed inappropriate.
I'm not sure that we have a set policy for newer, smaller, accidentally approved images. There is no source, this wouldn't happen to be a pixiv medium would it.
I got them from an imageboard, and found out later they were in moe.imouto (I always check iqdb before uploading because this sort of thing had happened to me in the past too)
That's why I asked HNT1 why he posted the samples instead of the originals.
