Comment on Beall’s List of Predatory Publishers 2013 by Prof.R.Sivakumar

It is a good list but why the journals in USA and developed countries are not analysed and listed, is it because they may sue the author immediately. Also the journal Hindawi was added some time back, suddenly removed, is it because of any personal reason? Why only journals from developing countries are being targeted and also only open access journals? Is it because the author is lobbying for the non open access journals ? How far this list is reliable is seriously questionable. I appreciate its a good work which is needed but the list is completely biased which is proved beyond doubt
