That headshot of a woman? You talking about a two word phrase that's real close to your domain name? The pic I saw is like you said, 600+ Plus circles and every article she's written is on the same "buddy" site (just found her site so she does write elsewhere on a totally unrelated niche).
now it's swinging back to the thin answer sites and G+ authorship
I tend to think, nowadays, that when it comes to article and forum spam, G has a floor and a ceiling for penalties; a few signature links on a 10,000 thread forum is spam, 300 links means you're participating in that forum - 5 or six articles is spam but 100 or more you must be a regular contributer.
When it comes to comment spam I know they aren't catching it.
