Frontiers Media was included in
Jeffrey Beall's list of
predatory publishers in 2016, though Beall deleted the entire
Beall's List after Frontiers and others requested his employer open a misconduct case against him. Among other practices, Frontiers sends out large numbers of unsolicited emails to scientists based on minimal criteria (submission of an abstract to a conference, for example) and then asks them to submit a journal article or even serve as an editor for the journal. ==References==
