"Predatory publishers or journals are those which charge authors a fee for publication with no intention of providing the expected services – such as editorial or peer review – in return. Charging a fee is a legitimate business model, but the publisher should be providing a good publishing service in return. Authors, realising that they have submitted their paper to a questionable publisher, can find they are charged a large fee if they want to withdraw their article."(https://thinkchecksubmit.org/resources/about-predatory-publishing/)
"Predatory publishing, also write-only publishing or deceptive publishing, is an exploitative academic publishing business model that involves charging publication fees to authors while only superficially checking articles for quality and legitimacy, and without providing editorial and publishing services that legitimate academic journals provide, whether open access or not. The rejection rate of predatory journals is low, but seldom zero. The phenomenon of "open access predatory publishers" was first noticed by Jeffrey Beall, when he described "publishers that are ready to publish any article for payment". However, criticisms about the label "predatory" have been raised. A lengthy review of the controversy started by Beall appears in The Journal of Academic Librarianship.
Predatory publishers are so regarded because scholars are tricked into publishing with them, although some authors may be aware that the journal is poor quality or even fraudulent but publish in them anyway. New scholars from developing countries are said to be especially at risk of being misled by predatory publishers. According to one study, 60% of articles published in predatory journals receive no citations over the five-year period following publication." (https://en.wikipedia.org/wiki/Predatory_publishing)

PREDATORY CONFERENCES
Predatory conferences exist to make money. Revenue-generating companies exploit attendees and presenters as well as charge high registration fees. The motive is not scholarly advancement.
The Himmelfarb Health Sciences library provides a very comprehensive check list to help ascertain if a conference you are interested in may be predatory. A site called Think Check Attend provides similar guidelines.
1. Check the accredited journals lists supported by the Department of Higher Education which are available on the Research Office website (not being on the list does not automatically mean publication is predatory but rather not met the standards for inclusion)
2. Bealls list provides a list of predatory publishers and publications. It gets updated
3. Google the journal name, add the word predatory and you can usually find an answer.
4. Use the 'think check submit' site
This site provides a check list to guide you in determining if your article has covered all the bases in terms of avoiding predatory publishers.
1. Check out the accredited lists of journals from the Research Office to find a journal to publish in
2. Use Journal Citation Reports to find a reputable journal. (see the page above on Choosing a journal to publish in)
