I'd say a lot of this begins in a sensible strategy of looking less juicy - you'd reasonably expect your opponents to weigh the pros and cons of attempting to take you out, and you can work against this in two ways - either to minimise the pros, using a scorched earth-type maneuver to make their conquests less useful, or to maximise the cons, by fielding a powerful defense that will cause losses, and by strengthening the enemies of your attacker.

This, of course, only applies while you still have a theoretical chance to survive to win the game - and, as far as I can see, some people ask that players, once they reach the (quite subjective) point of no return, immediately stop any such actions and let themselves be gracefully conquered by whoever is rampaging through their armies - I find this to be a bit much to ask.

Allow them instead to die as they've lived - to spit in the face of their executioner, as it were. Sure, it's not fun to have someone spit in your face, especially if it blinds you enough to give another enemy a chance to strike, but that is something a would-be executioner should be prepared for.
