I stumbled upon post #3077254 and noticed the bad_revision and downscaled_revision tags,
after reading the wiki, and investigating the source a bit, i believe that what it's supposed to mean,
is that the revision found at the given source as defects compared to the original, in this case, the source has a smaller version, correct?
In this case why shouldn't you update the source to point to the original image instead of applying those tags?
Or does it mean said source can't be found/known?

Let's say our pixiv url has a picture we'll call "Source A". Someone uploads source A to danbooru. Now danbooru has post A with source A. However later the artist decides to reupload the image on the same link, overwriting the source with a lower resolution version, which we'll call B. Now Post A points to Source B. In order to prevent people from uploading Source B again when Post A already exists with a better resolution, we use bad revision so that userscripts and automatic tools can detect when a post has a better version already uploaded, so frequent uploaders don't make the mistake of uploading it.
I said same link, because "bad revision" means the previous version of the same link is not available anymore - not publicly anyway. We don't use the bad revision tag to distinguish for example pixiv/twitter versions, only versions that come from the same link.
