I've recently flagged one post as a "low quality" post, well, because the "link only" answer option was not available in flag reasons. I'm talking about this post in which was a link to an external site, where was the answer to the asked question and so I don't understand why it was taken as a spam.
Could someone explain me, why that post was taken as a spam ?
P.S. I know the answer should be deleted but why just as a spam ?
