As I said, more and more of these junkers go to the "I hate Liberty" side, so it wouldn't be godmodding to ban all of them for the sake of keeping the peace and quiet. As you know, 99% of the community won't really want to get arrested so there is no formal or appropriate way to get rid of those that to RP as such. And junkers must learn that their actions have consequences.
Edit: Also why does someone have to be corrupt to have good RP? I find no flaws in LN's RP so far, and no one apart from those who start these posts really complains, give me screenshots of the faults and I'll correct them.
