Hey Jefferey,
Thanks for the update. However there are several predators you have missed. SciHub (scihub.org), they first used an address of Lasani Town, Faisalabad Pakistan but when I questioned them to confirm, they changed their contact details to a PO Box in connecticut. They also have major grammar errors and their website doesn’t work properly.
Another is AENSI web (aensiweb.com) they were first called INSIpub, then they changed to AENSI. They have a series of conferences which if you see are definately not authentic (they dont even have a url).
We have plenty like eSci Journals Publishing (escijournals.net). From the address you can see this is a scam. It is in a house in a town in Islamabad Pakistan. You can also judge from the quality of the website.
I also did a bit of a research on Bentham. They are actually based in Pakistan and the person behind it is Atta-ur-Rehman.
