Reviewer responsibilities are generally volunteer hours insofar as the peer reviewing the article isn't getting paid, or compensated in any way for the many hours/day(s) it will likely take to properly vet a piece of work. Therefore reviewers eventually blow off some articles, choosing instead to do a quick analysis and hope the other reviewers perform a more thorough analysis. Apparently, in the case of this paper, all the reviewers blew off their jobs.
