Daily hacking of text link ad networks

It appears that google has hired contractors to hack almost all text link ad networks daily wasting their time and money .
Till 8 January 2017, a link on a major text link ad network was not working and on 9 January 2017, the DA for all the websites listed with another text link ad network were reduced to zero
However the hacking of these text link ad networks is not covered by the tech bloggers, who only cover google, not their unethical tactics
