Is there short collusion

Guys I have been doing research on the relationship between short positions and negative articles on a2 in the NZ Herald. I looked at three articles, the one in March on Illuma Atwo competition, the one on the 23rd September regarding Jane's sales of shares and the one on the 7th October regarding Nestles competition in Australia

This is what I found and have sent to the business editor at the NZ Herald

Your article about Nestles competition which occurred on the 23rd March 2018, guess what short positions in a2 between March 23rd and your article in newspaper on the 28th increased from 719,000 shares short to 1,339,000 by the 28th or 85%. This just before your article. In addition your article on the 23rd September was predated by short positions from the Thursday through to the Monday morning after your article appeared increased from 23.178m shares short to 26.855 m or 3.57m shares and 15.36%. Then there is your article on October the 7th. Short positions in a2 from the 3rd to the Friday the 5th October immediately proceeding your article on the 7th increased from 27.758m to 33.157m short positions a whopping 5.39m shares or just under 20% in two days prior to your article.
