If you obtain a high volume of links that don't generate traffic it's a pretty good sign it's just a link building exercise.
If you're in 13,000 google+ circles but when you post there's zero interaction it's a good sign that's all been done for SEO.
If you place content underneath your footer that's a good sign it's not for users.
Looks like they've gone for it on all fronts.
