Interesting, and sad. FYI I did a whois search on the domain sprintjournals.com and it appears to have been registered by someone named Lorenzo Allovisio (or the reverse) back in July:
http://www.whois.com/whois/sprintjournals.com
There is no phone number or email listed for him, but there is an address that seems real:
Also, one other note on this: I looked at a couple of the webpages for their journals, and they do list at least one recent article for each. For example, their veterinary journal lists a paper with authors who appear to be real people, living in Nigeria:

It may not be hard to locate the person behind this effort, or to at least confirm whether the authors listed on the journal sites actually submitted to the journals in question, and who they dealt with.
Why do I care so much? Because I do the same kind of research in the field of journalism. For example:
Keep up the good work!
