Jim Boykin - Is Google Googling me?

Jim Boykin,

We spoke a few years ago and it started me thinking a certain way and building my site and links a certain way. It's worked well for me (I run a small online educational business). I've collected a few old domains from others, nurtured my own, and advertised/promoted without while staying under the radar. I've a question.

As background, we know that Google discounts the value of links from related sites. Well, to be more precise, they probably discount the value of large numbers of links from related sites. Google figures that two sites that share an IP address are probably related. So they would discount those links.

Do you think Mr. Google also considers the following as indicating that sites are related and so they are discounting the value of the links?

a Registered to the same person.
b Registered to people at the same address (physical or email).
c Sharing the same webmaster account
d Sharing the same adwords account
e Sharing the same adsense account
f From blogs that are part of the same google account.
g From blogs, adsense, adwords, and websites that share a common google account?

In short, how much research or googling is Mr. Google doing to value or discount links along these lines?

PS - Jim, I'm a big user and fan of your free tools. Especially the cool tool. Thanks.
