I just got a flagged answer on UX consisting only of a reference to a blog article with (seemingly) no link to said blog article. Hovering over the text, there's no link, nor is there link styling. I promptly deleted it, since what's the point of an answer about a link with no link?
Clicking through to the answer on the question page itself, turns out "a great article about SUS" was linked text. It wasn't a full answer, just a comment anyway, but it really would have been nice to know it was a "link-only" answer instead of a "vague reference to not a link" answer.
