Beall's list was a list of "predatory" publishers and journals that engage in questionable publishing practices such as charging exorbitant fees, not conducting peer review, and accepting low-quality or even fraudulent research. However, the list has been discontinued and is no longer maintained.

That being said, if a faculty member published an article in a journal that was previously listed on Beall's list, it does not automatically mean that the article is not valid or credible. The quality of a published article should be evaluated based on its content, methodology, and significance, regardless of where it was published.

It's important to note that the decision to discredit a published article and not give it merit for job promotions and considerations should not be based solely on the journal where it was published, but rather on the quality and impact of the research itself. Therefore, it would not be reasonable or fair to discredit an article solely based on its previous listing on Beall's list.

Thank you so much sir Ajit Singh for a very logical and comprehensive answer.
