I also find this thread offensive. However, I'm not going to lock it for the time being. The thing to remember here is that a particular game is distinct from a particular player, someone who was your staunch ally in one game may stab you in the back in the next one. Besides that, as long as there is not a set of commonly agreed-upon rules about notification of attack being mandatory in a given game, this sort of thread will come across as whining about nothing.

Further, this sort of thread is a prime breeding ground for vendettas, which are something that will absolutely not be tolerated. If you have a problem with somebody's in-game conduct, keep it to PM, email or the particular thread dedicated to that game. If you start making lists where you add up everyone who ever got the better of you in a game, even if it was through backstabbing, fine, but keep them to yourself. The moment you start airing vendetta lists on the public forum, YOU get on the moderators' watch list. If it spirals out of control, the proverbial ton of bricks is liable to fall mostly on the person seen as the instigator of any trouble.

Try to keep that in mind.

With the limited Dominions MP experience that I have (just 2 games of Dom2 long ago), I remember being backstabbed and doing some backstabbing myself and we all had a good laugh about it afterward.
