Little details !!
Well, to be honest, I don't have an actual dni besides the obvious stuff. Most of the time I just click follow without thinking much of it.
But here is an attemp of dni:
() You're one of those Berserk fans (make jokes like "Casca enjoyed it", Gennon, Farnese horse, harrass female cosplayers...)
() You take selfship too seriously and attack people who share the same character as you (calm down bro it's a drawing)
() You think that liking dark characters or media equals agreeing with them or can't be critical about it
() Don't respect people pronouns or gender
Basically, just be normal, don't harrass people and we won't have problems
