Edit: spelling 'Beall'

To add: Of course 'predatory' if proven, should not be tolerated. Also, guidance to the public from researchers isimportant so that a relevant criteria is needed to assess the intrinsic merit of the article or book.

Wake up! Publication is not only about distribution of information. It is a money making business. With so many publishers coming out of the market, it is normal to have competition. Big ones may try to eliminate smaller or starting publishers.

Who are the scammers? Aren't they the ones who ask authors to transfer or assign their copyright ownership to the publishers or journal? Aren't they the ones who sell for profit without sharing their income with the authors? Let the readers decide the quality of information they read.

Don't judge the quality of research on the basis of the name of the journal or publisher or indexer. This is favoring unfairly one business from others without the benifit of bidding.

Who is guilty of being GULLIBLE? Aren't they the one who judge publications on the basis of suspicion, "POSSIBLY predatory" ? Are we the researchers who judge on the basis of uncertainty? Why can't Baell simply say, "these journals are predatory." WHY? Isn't it because he doesn't have evidence that can stand in court? I read in wiki that Baell is facing legal charges from publishers and that his employer deny involvement.(search for Baell's list at wikipedia).

My goodness to the research evaluators who dismiss research articles on the basis of suspicion, "suspected predatory". Because of the evaluators INCOMPETENCE to prove predatorial, the authors are made to suffer by denying/disqualifying them certain academic ranks. God forgive them for they do not know what these evaluators are doing. Wake up goverment educational institutions!!

In case you missed this, DORA's advice is not to judge the quality of research articles on the basis of the name of the journal (or name of publisher/indexer). Search for "San Francisco declaration of research."

I feel obligated to comment here. Based on my experience, I do not agree that LAP is a hoax or a scam. I already published one book with LAP. My book can be viewed in various online book sellers including google books, amazon france, amazon japan, etc. To test, I purchased my book via amazon.com as ordinary customer. I received the book and it appeared good. Before publication, I was asked to buy my book with them in order to reduce the market price. I opted not to release a centavo thinking that the blogs are correct about LAP being a scam. LAP did not force me to buy my book with them and good they publish it even if I did not buy a single book prior to publication.
As to the contract. It says, copyright is retained by the author. The author can republish in part or in whole the contents of the book. However, the Author is deemed responsible for the contents of the book. This is fair enough because the publisher offers free publication. So, being responsible, I have to edit and format it well, i have to ask some peers to review my work before submitting for publication. Flaws are expected in any first edition, however minimal, this is one provision for next edition.
I am working with my next book with LAP. We are still in the editing and formatting stage. Again, reading the contract that I am responsible of the contents, I have to be careful. This second book of mine is rooted from my dissertation. This has been edited and reviewed by dissertation experts in our graduate school.
In conclusion: LAP offers only free services of publishing and distribution. Major editing and responsibility of the contents are given to the Author. Thism I believe is the reason why LAP does not ask payment. Fair enough.
As to royalty. Well, my first book is not a best seller. First year I did not receive any. The second, only voucher worth 24 euro because according to accounting only 7 people bought my book.
