Nothing scientific. An attorney sued me and won using unethical methods that he has been sanctioned for in federal court before. Sufficient time has gone by that he would have no idea whom would be moving the legal sites containing the legal cites and case histories up in the serps, especially since he obtained an unenforceable judgement against me he has lost another ethics case in federal court.
Beginning on 11/23 I began building links with GSA to seven case law cites in which this attorney is the defendant de jure and which the attorney was found to have used illegal methods by the courts. To date I have only built about 14,200 links. The links are 70 percent unique, spread across seven different legal citations and pages, using partial match 10%,. secondary anchor 10%, branding anchor 30 % and LSI anchor 20 percent - all of which have seven to ten spun variations of the attorneys name or business name.
By 12/08 I had moved three of the target url's to each of the variations of the targeted anchor text.
On 12/09, the targeted URls began falling off the first page. Several of the targeted url's are on the second page, and two of the targeted urls have fallen to page 5.
