I guess I’ve got used to academic spam — invitations to publish in predatory journals. They typically scrape conference programmes, but today I got a surprising one:
I congratulate you on the paper “<paper title>”, published in the “3rd ISA Forum of SOCIOLOGY 2016”. Observing the relevance and contribution that the paper has in the field of study addressed, after analyzed by our editorial board, I invite you to publish it in <journal paper>Mail
Yes, it took them five years to “read” the conference paper. We also get the usual nonsense of being invited, and pretension of the journal being important, but the time lag… I’m sorry, you’re simply too late.
