When I wrote about Flags that don't have a valid Reference link, I meant "not valid" from a webbrowser's perspective: The link doesn't exist (anymore).
The description on my Trust Flag viewer is better: "Reference topic does not exist".

Many Flags have a Reference link with invalid content, but I can't highlight those without doing it manually.

I have suggested before that I can allow users to add comments to my Trust Flag viewer, but haven't had any feedback to this.

I don't really get why LFC_Bitcoin uses my topic on scammer BetKing.io as a reference topic for a Flag on game-protect.
