Reading the article, this is about CITATIONS which are trivially verifiable.

This is just article publishers not doing the most basic verification failing to notice that the citations in the article don't exist.

What this should trigger is a black mark for all of the authors and their institutions, both of which should receive significant reputational repercussions for publishing fake information. If they fake the easiest to verify information (does the cited work exist) what else are they faking?
