The best thing you can do is create more positive/constructive posts...and the let the trolls sink into the depths of the forum, unanswered and alone.
This is the best thing I've read all morning.

I'm wondering if the mix between RTS and 4X gamers here on the forums is contributing to the toxicity; you've got two very different player bases with different tastes in playstyle, from pacing to scope, and
Sins, as a genre-bender, tries to compromise between those playstyles with varying degrees of success. So, depending on which side of the fence you come to
Sins from, different aspects of the game frustrate you--as might, I expect, the subset of the player base that said aspects are designed to please.
(That being said; I think this game, while not perfect, is brilliant; and I am trying my darndest to hook my entire local gaming group into massive
Diplomacy-style galactic backstab-fests on large maps. Great fun!)
