It could be that Google Scholar weights citations differently when using them for ranking articles. However, third parties parsing Google Scholar cannot identify any distinctions.
Due to these recommendations we decided to withdraw the submitted papers.
It has to be mentioned that we published this book under our real names. However, it would have been just as easy to publish it with a fake identity (though this would have violated the terms of service of the print on demand publisher).
