No written rules are going to change it.
In the end, it's the behavior of the people in the arena that set the tone. I've been in a few times lately and it's been good fun, with good fights and folks being respectful about it.
As long as the regulars don't get into "MA flyer bashing" or using the excuse that the "MA Tard HO'd me so I'm gonna do it back" excuse, the new folks will get the idea.
Play it the way you want other folks to see you play it. No one else can make you HO, gang or ack run. It's in your hands how you handle it.
