Regrettable that the article begins by outing a prof from an unheard of university in India, who probably publishes in low repute journals and conference. Ideally the citing malfeasance score should be weighted based on journal and conference reputation.
And how do you measure journal and conference reputation? Conventional measures there also lean on citations, and journals have been known to do quite a bit of manipulation to get those scores up.
Start with Google Scholar's list of top publications: https://scholar.google.com/citations?view_op=top_venues, and detect self-citing and citing rings within the universe of these publications. Almost certainly the guy with the record for self-citing doesn't have a paper in any of the top publications.
