We read spam a lot: prospective cohort study of unsolicited and unwanted academic invitations.

Abstract

To assess the amount, relevance, content, and suppressibility of academic electronic spam invitations to attend conferences or submit manuscripts.  Prospective cohort study.  Email accounts of participating academics.  Five intrepid academics and a great many publishers, editors, and conference organisers.  Unsubscribing from sender's distribution lists.  Number of spam invitations received before, immediately after, and one year after unsubscribing from senders' distribution lists. The proportion of duplicate invitations was also assessed and the relevance of each invitation graded to the recipient's research interests. A qualitative assessment of the content of spam invitations was conducted.  At baseline, recipients received an average of 312 spam invitations each month. Unsubscribing reduced the frequency of the invitations by 39% after one month but by only 19% after one year. Overall, 16% of spam invitations were duplicates and 83% had little or no relevance to the recipients' research interests. Spam invitations were characterised by inventive language, flattery, and exuberance, and they were sometimes baffling and amusing.  Academic spam is common, repetitive, often irrelevant, and difficult to avoid or prevent.
