A graveyard is not enough. I'm in an argument with someone and even if I put my thread in the graveyard and tell him to leave it alone, he's like "Just because the thread is in the graveyard doesn't mean it's dead", and continues to fuss over the thread. So, I gave him the link to the graveyard rules and he still won't listen.
I keep telling him the same point all over again and he doesn't understand so that makes me really just want to delete the thread.
Somebody might make a troll thread and break the rules with foul language. Then they will delete it and Spiral knights can't catch it. It will make the forums dangerous.
If you want to stop a fight that your having and he continues, send a support ticket to lock a thread
