I understand your frustration with trolls. I don't appreciate their posts and also think that it's damaging the reputation of crypto currencies in general.

The only way that seems to work against trolls, is to ignore them and don't feed them with your attention/reaction. Trying to stop/fight them, just adds fuel to the fire.

They don't need logic to achieve their goal. They just want to disturb. If you react emotionally to them, they won and it also makes you susceptible to the use of the same behaviour they exhibit, as a last resort to win the fight which cannot be won by reason.

If we don't feed them, they don't get their satisfaction and eventually will stop. So it is in our hand to stop the trolling by acknowledging that we, who react to them, are responsible for keeping that behaviour alive.

Or like Joshua from Wargames put it :" The only winning move is not to play."
