Problems with MD5 search for normal members

Not too sure how to explain the problem, but I noticed if you do a md5 search for a picture already in database, it doesn't show the tags related to the pictures, even if the picture exist. It's only really a problem for normal members since we can't see questionable/explicit picture thumbnails in md5 search result.

for exemple, I looked for
md5:ff216c23b6aa86775ad2209dcc33a2bf
before trying to upload it, and it didn't display any tags or image, but it already existed.
But for safe pictures like
md5:c9427d13e205362526c0c7858976941f
it still won't display tags, but we know picture exist since we can see the picture thumbnail.

I guess the best way to be sure a post exist for non-privileged users is putting the hash on it's place

Yeah, but isn't it a bit bothersome to do? Don't think it's meant to be done that way

I don't see it as being much more troublesome than typing it in a text box, the only difference is that you have to type the extension and you can't see the tags for either post. Seems tolerable, at least until you become privileged.
