People HAVE tried to resist that kind of behavior from certain official members, but when they did they faced the wrath of the entire official faction, and also oorp revenge from the enemies of the faction (probably the same guys or their friends).
I'd be all for complaints with screenies on the forum.
But most of the guys who get insulted like that dont usually post on the forums.
And if they do post... well... "trialbyforumz Q_Q lolwhut iB4tl who are you noob anyway".
You would need someone with enough experience and forum activity to post it in a presentable way.
Some have.
But ohhh man...
Some NASTY sh*t happened there, I tell you.
Use search function on "Akumabito".
And a few more names that spring to mind.
Skype + power to hand out goodies and favors = army of unscrupulous <strike>oportunists</strike> "friends" that will do pretty much anything for you
Part of the problem is that this sort of poor behavior that you mentioned is that persons way of gaining reputation and doing favors in that faction.
