Several times a week my email inbox contains offers to contribute to journals in subjects like engineering and agricultural sciences and in many other fields. The emails look legit, but my red flags go up nonetheless. I’m not an engineer, nor do I work in agriculture, or most other fields. I’m a geologist and paleontologist, and I teach geophysics, astronomy, oceanography, and meteorology, but I don’t work in every field of science. Clearly, my email address (which I willingly gave to legitimate scientific organizations) has been added to a compilation of scientists’ email addresses and sold and now every scam “journal” will spam me with these emails, not worrying about whether their “journal” is in my field or not.
