Could you possibly exaggerate any more? 10%? Really? With the multi column newsfeed on Google+ it's just impossible that you see less content than on Facebook. And how does your comment have anything to do with the article?
One of the points of the article is that it's hard to tell and control what is happening on the Google+ interface and system. Add A/B testing and rollout of new features, utter lack of accountability and bugs, and probably no one in the world can ACTUALLY TELL if the alleged abuser actually sent an invite.
I was a little skeptical of that part. Is it really that easy to accidentally invite someone?
