Now this is garbage. However, the attached link was legit. It answered the question directly, not adjacently as many spam links do, nor was it a link to an ad farm (such as the usual social media click-baits.
I removed the garbage text, leaving only the link. Then I posted a comment asking for a summary of the article as link only responses tend to disappear.
While there are certain elements of spamousity in this post, I don't see why I was suspended from the review queue for a day because of it. (I'm not fighting the suspension. It's one day -- who cares.)
Suspension to me is an accusation that I did something wrong, or so carelessly that I was negligent in my review. I don't believe that was the case.
TL:DR; Link was legit, not an ad farm and directly answered the question. Why was I expected to identify it as spam?
Edit: Added Options in Review (from SO, as I can't access the DIY queue right now).
