Hi Charlie,
First off we have tested a lot of those, and here is what we believe and tested to death. Same as Google knows your personal traffic habits, and about everything there is to know about your websites etc, they know a real user vs a fake one. Anybody who has local clients can probably chime in here, but leaving reviews for local business is getting very tricky if you are gaming the system. Why, again, Google knows a real user vs a fake one... they are that good up to a point. ...So how does that relate to us? We only allow 9 account TOTAL to be added to your personal client. We will scrap news daily to find normal stories etc that people share in real accounts, and post them to the accounts that client is managing. Our entire aim is to almost build up the PR of that user over time. We fully believe Google has some VERY ugly plans in store, mostly based on a sites traffic stats, as time spent on site, bounce rate are super easy for them to track. So with a full network of REAL users on REAL IPS, we can totally crush these indicators that A, affect us all today and B, we think in the future will be beyond critical. , sorry to be long winded, but hope that helps a bit.
