I don't think it's "gang up" syndrome to point out that many players, yes even experienced ones sometimes, have an irrational fear of buying an embargoed card. Even on a board without trashing or pseudo trashing, one, heck even 2 dead cards aren't going to ruin your game, but a lack of economy will.
If you're scared to buy silver, how do you plan to hit 6? Or 5 with consistancy? One good hand is better than two poor ones. As long as you don't draw your silver and curse together, you're probably better off.
I don't think "not playing with embargo" is a fair answer. It's a strategic element to play, like any curse giving card. I can't see how, even from a late position in 3/4 player it would play kingmaker, ESPECIALLY on a board that did have a means of dealing with the curses.
Look, I'm as guilty as the next guy at failing to these same mistaked from time to time. But I'll be darned if I blame my opponent for something in my control. You'll never learn with a "It wasn't my fault" mentality. We're not here to gang up, we're here to offer advice so that the community improves. I enjoy good competition, and like seeing strong play. But if you beat me, I want to know what mistakes "I" made.
