Apart from my reputation, so no need to put the publication on my CV but here is a platform where I don't have to pay any Article Processing Fee, My work is indexed on Google Scholars and is freely available to the public in few days.
You need to publish in journals you are sure your colleagues in your desired and current networks will read. Predatory journals are impact factor catchers.
Thanks for the answers so far. I wish ResearchGate will allow individual reply. The idea was actually to further understand the motivations for publishing in predatory journals
@Jorge Enrique Delgado, you raised a valid point which I just have to agree with, publishing in journal my colleagues are more likely to read, however I think the paywall may also limits some of my colleagues reading it unless it is open access.
@Stefan Gruner, As I acknowledged, It appeared that the main thing to lose and seems to often discourage scholars from publishing in in predatory journals.
@Anja Hühnlein, Thank you for the advice, it seems the peer review makes the research worthwhile and impactful. So will surely lookout for those platform.
There are many things to lose by publishing your work in predatory journals. As others rightly said, your work will not be peer-reviewed and no scientific input will be made to the manuscript. Again, it may never be read and/or cited by other scholars.
I also want to add that it is even those predatory publishers that charge fee because they are established to make money. I have experienced this twice before I learnt how to choose where to publish my work and I paid heavily. So you do not only lose reputation, one loses financially too.
