Yes of course, and that's why all of the blog networks and other SEO services advertised here fail.
So, if you can be bothered to read, and most importantly think, then even if they infiltrate this network they can only take down 1 cell, not all cells.
If 1 cell is hit then I create 3 new cells, one for each member, and we see what happens then, or I just ban those 3 and we know that one of them works for or is supplying details to Google.
The only weak link in this system is ME - if Google can identify me and "snoop" on me and the sites I visit then they can uncover the whole network, which is why I will NEVER visit ANY of the sites in the network.
If I want to check if you've added my links, or someone complains you're not doing X, Y, or Z then I use a VA sourced from a variety of places, of a vairety of nationalities, and give them a variety of tasks so it's not balck and white.
Rest assured that I have thought of this from every which angle you can think of to avoid any holes or problems or ways that Google can unravel even a tiny percentage of the network.
I anticipate that they will find some, but that will be because of the stupidity and lack of forethought of other people within the network - hence why they only have limited visibility so they can only do limited damage, and why they can be kicked out when they feck up.
The idea of a network that breaks Googles rules where the sites are completely open and easy to find and advertised openly on open forums like the ones that have been recently hit is one of complete idiocy and is guaranteed to fail.
