Honestly, I don’t view this act as a “prank,” but a dishonest act. If the prankster was serious about testing the integrity of the publisher, he could have waited for acceptance but refused to pay the OA fee.
Second, I doubt that the editor of an African journal would catch on to a joke routed in Indonesian popular culture.
And last, to a non-Indonesian, this paper looks like a legitimate submission.
In sum, there is little to learn from this act except that this African journal does not use a plagiarism detection service, like CrossCheck. I don’t think it means anything about the state of open access publishing.
