Very interesting analysis of a recent google patent filing:
The Google Rank-Modifying Spammers Patent
From the patent:
The rank transition function provides confusing indications of the impact on rank in response to rank-modifying spamming activities. The systems and methods may also observe spammers' reactions to rank changes caused by the rank transition function to identify documents that are actively being manipulated. This assists in the identification of rank-modifying spammers.
For example, the initial response to the spammer's changes may cause the document's rank to be negatively influenced rather than positively influenced. Unexpected results are bound to elicit a response from a spammer, particularly if their client is upset with the results. In response to negative results, the spammer may remove the changes and, thereby render the long-term impact on the document's rank zero.
Alternatively or additionally, it may take an unknown (possibly variable) amount of time to see positive (or expected) results in response to the spammer's changes. In response to delayed results, the spammer may perform additional changes in an attempt to positively (or more positively) influence the document's rank. In either event, these further spammer-initiated changes may assist in identifying signs of rank-modifying spamming.

I've spent the last 59 months building 412 MFA sites. Each site averages 8 cents per day...I said average, some make up to 17 cents per day, PASSIVE INCOME! This income allows me to live comfortably and buy ANY flavor Jolly Rancher or Skittles I desire. Don't give in to fear, it CAN be done!
