Dear Jeffrey!
There is a small typo in the link to the fake Jökull: it should read “jokulljournal” instead of “jokuljournall”.
A bit off-topic: the fake “Wulfenia” operates with a faked editor-in-chief: Prof. Dr. Vienna S. Franz… yeah, right… but:
I fail, however, to see that this journal is somehow connected to Tomas Publishing. I did some quick look-ups on builtwith.com, and it does not seem evident to me that Tomas Publishing hijacked Wulfenia or the journals you mention. While some of those journals share some similarities, they use different architectures, different name servers (okay, understandable). I would have expected some more hard- and software conformities for all of them. Allright, most of them run on Apache web servers, but I do not consider that unusual. Most of the hijacked journals are registered in the US, according to “Whois” searches.
Can you elaborate on the reasons why you think these are similar, apart from the pirated images and cheap looks?
Cheers
Margaret
