When this Game was created, it was meant to resemble the "real world" as much as possible, specifically of course the way warfare happened in the real world.
I think it has succeeded remakrbaly well; reason why we are all more or less 'addicted" to this Game.
During World War 1, World War 2 and you name every other war in history, their participants most certainly included numerous Douche-Bags, Maniacs, raving lunatics, mass murderers, megalomaniacs and, who knows, perhaps also a sprinkling of "really nice guys" who wage their wars as if they were at a genteel County Cricket match and who wail loudly in terms of" I don't want to play with YOU any more", just like 15-year old school-girls do, whenever someone else did something that didn't meet their fuzzy abstract and ever-shifting ever-so-noble codes of conduct.
What we are seeing here in this thread is that many players feel that douche-bags and weirdo's should somehow be banished (ethnically cleansed, perhaps..?) from this game, and possibly from this earth as well.
Many excesses have of course resulted throughout history as a consequence of this otherwise very understandable (?) and noble (?) pursuit.
The facts are: The world, and WebDiplomacy, is/are full of weirdo's, creeps, crooks and vagabonds, and sure as apple pie that will never change. Live with it, I'd say!
I for one would much rather play Web Dip with all kinds of strange and colourful characters than with prissy tight-assed preppy whiners, full of their Righteous Indignation and Monica Lewinsky-like "bitter tastes in their mouths", but who are basically one thing and one thing only: bloody boring!
