OWG's right however its always harder for the big G to prove 3 way links.
Lets say i link to your directory from my spurs site, then your directory linked to my directory, all coming from different C class ip's , and different Who is info ,how is google going to prove that this is a 3 way link ? they cant ! as long as you dont do it over and over again i cant see how they could do anything. Apart from maybe bringing in another factor that means links have nothing todo with inter linking and is purly todo with content. Of course this would mean that google would have to manually review every single site and would be be effective, so thats not going to happen
