The Robber Barons is a Tepper graduate-student written publication that is issued every week (or at least tries to be). From everyone who talks about it, anything can be written and published in it - and the direction normally taken with the publications is usually supposed to be funny. Some hit it. Others tend to miss and fall a little into the nasty territory.
There was an article in the Robber Barons this week that was interpreted as falling into the nasty territory. A first year wrote an article about things that annoyed him and specifically mentioned a fellow classmate (dubbed the "Tiger Mom") who, according to him, was irritating and asked stupid questions in finance presentations and constantly posted articles on the Admitted students Facebook page links to articles that have no interest to him. Said classmate took offense, unFriended him, and subsequently showed a picture of her dog having chewed up the article on the Facebook page.
According to the editors, anyone is fair game to be called out and made fun of in the Robber Barons. When I read the offending article, I had no clue on who it referred to (since I don't go to finance presentations). I had to be clued in on this controversy :)
