In truth, there are a lot of dubious journals out there. Some of them don't even bother with peer review and will publish your paper or register a DOI as long as you pay. In Korea, we use classifications like SCI or KCI, but strange journals like this still slip into SCI as well. As mentioned previously, 'Frontiers in Cell and Developmental Biology,' the journal at the center of this case, hasn't enjoyed much trust in its field for some time.
