I have also received a couple of these, I have just noticed.
For sites that have been considered authorities on their subject and have never had any links bought what so ever.
There are so many links to these sites, it is silly to even try to contemplate which ones Google considers unnatural.
As if that is my problem anyway.
I wonder if there is a legal case here against Google for any loss of traffic due to unnatural link penalty.
They are sort of admitting a penalty only on conjecture.
Wouldn't the onus be on them to prove that links have been paid for?
