Fkey is entertaining as usual but I recommend trying to not upload almost the same pictures twice or even more. Perhaps wait for a higher quality version or just sometimes don't upload an image which isn't noticeably better quality. IMO this one should be uploaded first or not uploaded at all. Try to not make a mess of Danbooru. Maybe it would better to replace old image with a new, barely different one?
Oh, and for some reason I currently cannot download either of these two drawings in full size, my Internet browser writes "Failed - No File". I can download samples. Other pictures I try to download are working correctly.

1. There is a forum on which you can argue your point about site policy.
2. Image replacements are only used for image samples, not revisions or even different sources.
3. The Sonohara server is missing a bunch of images, I would strongly suggest using Hijiribe for a while until that gets smoothed out. Should be fixed now
