It is increasingly clear that google is only targetting wordpress blogs for deindexation in 2017 . Some domains which were deindexed in 2015, 2016, were reindexed again, including wordpress blogs in September 2017.
However they were only indexed for 10 days, and the wordpress blogs were again deindexed as they are competing directly with google adwords. The google competitor is under surveillance so that her websites can be easily located and deindexed especially by hathwar, kodancha, caro, nayak, mandrekar
However the domains which were converted into static websites after being deindexed, remain indexed , indicating that only wordpress blogs are targetted for deindexation by google in october 2017, static websites which make very less money are not targetted.
