Is the MDPI a Predatory Publisher or is the MDPI a Victim of Extortion? Who Are Other Victims of Fake Blogs (Pseudo-blogs)?

Abstract: Recently many articles have been published about which Publisher is predatory and which is not. Two controversial web sites existed: a) http://scholarlyoa.org and b) http://predatoryreports.org The first Jeffrey Beall's list was closed by the academic authorities of the University of Denver after strong pressure from MDPI in the year 2014 and from Frontiers in the year 2017. In the meantime many legitimate and genuine peer reviewed publishers have been victims of this blog's suspicious policy. On the other hand predatoryreports.org was anonymously owned and which had taken Jeffrey Beall's list and made it a flag. Recently the controversial predatoryreports.org has been hitting MDPI, FRONTIERS, HINDAWI in a very slanderous way. There was even a site on Cabells Index that said the owners of the http://www.predatoryreports.org were asking for money from publishers to remove them from the http://www.predatoryreports.org. Actually they were blackmailing the Publishers But a few days ago that site was shut down (they shut it down). Regardless, all this has influenced some academicians in some countries to consider MDPI, Frontiers, Hindawi Journals as Predatory or semi-predatory.
