The thing you have to realize is that by behaving utterly loathsome both in and out of the game all you accomplish is making sure people don’t want to make pacts with you in the future, or indeed even play with you - and perhaps if you’re lucky annoy some people who are playing a game with you for no reason other than mutual enjoyment. Take this advice in the spirit with which it is intended, regardless of how you justify it poor sportsmanship and being a sore looser hurt yourself more than the people you’re trying to annoy. If you behave like somebody you’d want to play with you’ll have a much more satisfying game, and indeed life. Fight the good fight, congratulate your conqueror, and see if there is anything you can learn from your defeat.

By definition its strategy to avoid a fair fight. By definition it's poor sportsmanship to cause grief after you've lost. You decide the player you're going to be.

That’s just my opinion, so don’t bother responding with vitriol as that’s all I’ve got to say about it.
