We have only the power to telling people to become aware of frauds and we cannot make people not invest in them. So if we do our part, I think thats enough for one human to do their part than waste time on trolling trolls.
I'm content to do both, heh. The arguments in support of Bitcoin are nearly self-evident at this stage, so it can get a bit stale repeating the same things time and again. It's refreshing to open fire on an unsuspecting troll every once in a while. Like how people appreciate a floorshow with their meal sometimes. Adds a bit of extra flavour, heh.
