You don't have to name change to behave in a troll like manner. The forum has been flooded with post which have created enjoyment for some taking part and many negative emotions for those that had no idea what was happening and created a paranoid environment.
I think its a shame, but it must happen all the time, so you need to understand that stuff like this happens and have break fro MN. If you are new, it must be very odd to figure it all out.
to quote "It would be nice if everybody was easy going, but stuff like this does discourage people. Established posters may leave a message board because of the arguments that trolls ignite, and lurkers may decide that they do not want to expose themselves to abuse and thus never get involved."
And I have never really disagreed with some of the posters here, but I do now.
