if you let a stuffbird stick around being stuffty then regardless of whether the community actually condones his behavior or not people are going to follow his example
like, let's say i go around stuffting all over people's artwork in gallery. if i'm in the right, people will see my actions and go 'oh man bushido's so cool telling that guy his stuff is stuffty i'm gonna stuff all over people just like him', but if i'm in the wrong people will see my actions and go 'oh man bushido's getting away with being a huge stuffbird, that means i can be a stuffbird just like him and no harm will befall me'
but if some harm actually befalls me for being a huge stuffbird then it becomes clear to the community that my actions should not be replicated, cause you'll just get kicked out
