@robert, I do not say that we need to go black hat. On the contrary, but it is interesting to see what they are doing because they find loopholes and use them as much as possible until their sites are sunk, which is fine with me. We all loose when they use that kind of tactics. They do have some smart guys and it's too bad they don't go white hat instead.
A lot of Googles problems are from these guys since Google have to defend themselves every second of the day against attacks from black hatters and we are mainly collateral damage.
I am not looking for a 12 step to gaining #1 position in Google. I know there are a lot of sites and you have of course Google Guidelines but maybe we can come up with some white-hat rules like "Honesty is the best policy"?
