Thanks for the interesting link, Michael.
One of those incriminated journals actually features this information on their home page:
Review Process
The International Journal of Advanced Computer Technology (IJACT) was developed for Engineering, Engineering Technology, and Industrial Technology professionals and is a highly-selective, refereed journal. Manuscripts that appear in the IJACT Articles section have been subjected to a tiered review process. This includes blind review by three or more members of the international editorial review board followed by a detailed review by the IJACT editors. Although feedback ordinarily will be given, the editors reserve the right to reject a manuscript for publication without a rationale for their decision.
"blind review" indeed. The reviewers of the "Get Me Off Your F****** Mailing List" paper must have read it blind-folded.
But then, the journal editor had obviously blindly accepted the "fee of $150" paid by the submitter.
On a more serious note, and I say this as a (former) researcher, I maintain that it is an integral part of serious scientific/academic research to assess the validity of those journals where you submit your papers. Some rules of the thumb include browsing those articles already published, browsing the Editorial Board list, and obviously rejecting those publications asking for a fee. This should be part and parcel of a training course for young researchers.
