Its crazy, how upset some people can get about losing a few dollars. I have pointed that out multible times in microstakes tournaments. Like "hey dude, we are playing for $3.3 here, so calm yourself down".

Many, Americans especially, take even Play Money pretty seriously on
pokerstars and Replay - probably because it's the only choice some of them have to play odd mixed games (or in some States poker at all).
It has happened several times that people are called out for playing like idiots or morons because they don't make the correct decisions - in not a Micro Stakes Game, not a Freeroll but a PLAY MONEY Game.
I can tilt and throw a horseshow or snowball if someone gets lucky at any stakes - but usually have the chat off, both for my own concentration and to not write something stupid when upset.
But some people can't tolerate losses at anything without going totally crazy. They probably throw the board out the window if they lose at Monopoly.
On the other hand, some people really deserve some disciplinary actions (strange than not more terrible things happen in higher stakes):
