I'm uploading a comic hosted on a Naver Cafe group. When uploading, I go to the Naver Cafe post, copy the image URL, paste it into the field on the Upload page, and replace the source URL with the post's URL.
When I used this method today, the comics would automatically get tagged with bad source. This did not happen the last time I uploaded them, which was 18 days ago. I thought that maybe the site started supporting the Naver Cafe groups recently and would now normalize the URLs, so I tried replacing it with the image URL. The bad source tag was removed, but the bad link tag was added in its place and the URL was not normalized.
I noticed that other uploaders also have their Naver Cafe posts tagged with bad source, so it's not just me.
This is the page I was uploading from. The affected posts are:
