I have been approached by Lupine staff twice, asking me to write an article for their "Current Trends in Computer Sciences and Applications". The first time, I complied, as they were requesting a short text for their first-ever magazine; the second time, I sent a longer text ("review article"). Both times I insisted I would happily write for them, but would not be paying them to publish me -- and yes, after some insistence, I was "waived" 100% of the processing fee.
So far, so good.
However, for my second article, it was:
- Not peer reviewed, but published just as I sent it. That's not acceptable practice for an academic publication!
- In order to fit their style, my manuscript was mangled; paragraphs were cut and joined with no regards for readability; mathematical expressions were rendered incomprehensible; related figures were separated.
I have contacted them repeatedly, pointing out the issues I found (and that leave my work in bad light!), but have been downright ignored.
