 In February 2015, a longstanding Wikipedia administrator was site-banned after Wikipedia's Arbitration Committee found that he or she had, over a period of several years, manipulated the content of Wikipedia articles to add positive content and remove negative content about the controversial Indian Institute of Planning and Management and its dean, Arindam Chaudhuri.An Indian journalist commented in "Newsweek" on the importance of the Wikipedia article to the institute's PR campaign and voiced the opinion that "by letting this go on for so long, Wikipedia has messed up perhaps 15,000 students' lives".The 2005 "Nature" study also gave two brief examples of challenges that Wikipedian science writers purportedly faced on Wikipedia.
