Since you asked, and since I clearly can't get enough of this fascinating conversation, here's my take on that particular bug which is up your ass.
I've never built a blog network, but if I did, I would try to do everything I could to make it not look like one, i.e. random, even a little fucked up and amateurish on some sites. Each site would be quite different (platforms, writing style, reading level, images, etc). I would certainly not block all link bots on any of them, even if some random nitwit on some forum assured me it wouldn't get me deindexed. Because, who does that, except people who are seo'ing and don't want their link profiles tracked down?
thehobbster actually wrote an interesting thread about blog networks a little while back (complete with pictures!), which I would find and link to for you, except for the fact that you're a douche.
You're still entirely missing the point, however, but I'm quite confident you will continue to do so. And, I really need to get back to work, despite how fun it is to converse with you.
Best wishes for continued success.
