You know, I don't think many people understand the idea behind Don't Feed the Trolls. Though perhaps that's just that the Internet has changed or something, I don't know.
I mean, look at people like Chris. If he had just gone "Oh jeeze, a mildly embarassing photograph of me is on the Internet. I'll just ignore it and wait for people to forget." then... This forum would probably not exist, and he'd probably be a hell of a lot more content in his life (Excluding IRL shit which would, of course, have kept on happening.)
Instead he launched a one man crusade to beat the Internet and prove himself the Superior Gentleman.
To me, that's what don't feed the trolls means. It means that when you fail to hide your power level and embarrassing shit happens, you just ignore it and let it go away.
Or take SnapeSnogger, when you go to a forum of professional artists and art students and they critique your work, you don't try to get your fans to start some sort of war with them.
Or, on a broader less individual level, it means that when someone walks into your Steven Universe fandom forum and says that Steven Universe is shit, you don't engage them because they are trying to get a rise out of you.
It doesn't (I'm going to give Brinna Wu the benefit of the doubt here, so sorry to any hard anti-Wu's that bothers) mean that when you are getting death threats, that you sit silently and take them.
