I noticed this link-only answer and thought I should flag it, but discovered that "link-only" is not in the criteria under the "I am flagging to report this answer as... " "Not an answer" option. Does this mean we should not flag link-only answers, or click the "Not an answer" option, or enter "Link Only" under the "In need of moderator intervention" option?
I thought I would find a answer here or on the mother-meta, and there certainly are related questions such as "Why was my flag on a 'link-only' answer disputed?" or "How to flag link-only answers / what happened to the very low quality flag?", but to my surprise I could not find a simple, clear answer.
