i have a question about this. i've been reading that it's possible for Google to prevent a site from being able to pass link juice if they suspect that that site is blatantly selling links. now, let's say that i found a blog on TLA that is selling links. do you think that Google has their own "reviewers" or engineers that sign up for a TLA account, then find all of those sites which are selling links and de-weight them for doing so? i know i would if i was Google, but i could be wrong about this.
