This site provides lists of conference marketers that lie, cheat and steal. In other words, those that have come to be known as ‘predatory.’ The lists are simplified, modernised, transparent, and above all justified. They are kept recent (within three years of the present) and presented in a readily understood way.
University librarians and other relevant officials who provide guidelines and warnings about predatory conference promoters should consider augmenting their advice in the light of this new resource.
As regards the academics, some are victims of identity theft, some are willing collaborators with the scam scholarly publishing industry. Most are not forthcoming on the issue. There are copious notes that might help in a preliminary diagnosis.
