He and his blog have been featured in The New York Times, Nature, and The Chronicle of Higher Education. Last year, OMICs, an Indian publisher Beall added to the list, threatened to sue the librarian for $1 billion.
Further making MDPI a rare inclusion on the list, Beall once published a paper in a MDPI journal.
“Before he became known for his valuable ‘list of predatory publishers,’ he submitted an article to the journal Future Internet, which was published after peer-review,” Rordorf said in an email. “As in many cases (more than 30% of our articles), Mr. Beall was not asked to pay publishing fees for his paper.”
Rordorf said, until this week, the publisher had never received a complaint from Beall regarding its editorial process, but Beall said he now regrets publishing with MDPI.
“I think it’s fair to classify MDPI as a questionable publisher, and as such, it belongs on my list,” he wrote on his blog. “I recommend that all scholars not submit papers to this publisher. In the long run, publishing a paper with MDPI will turn out to be a bad personal decision for most authors.”
In an eMail to Beall, Shu-Kun Lin described the blog post as “crazy,” and said he would be contacting the librarian’s supervisors at the University of Colorado.
“Many of the allegations are totally silly,” Rordorf said.
