Well, I think there are 3 potential solutions.
The first one would be moving on. Usually in high school there is that one year where everyone goes to idiot mode and starts acting extremely naughty, arguing, fighting, overreacting and generally being drama queens. At the last year of high school, it's usually the best one. It was for me anyway, everyone was just more mature about everything. And if they still maintain that behaviour, well, you can probably guess how they will end up later on in life. Just don't be passive agressive towards people. This is in general really. That is the antisocial behaviour that people who aren't jocks usually have, and it's nearly as bad imo. However, if you got the ball rolling... it is kind of hard to stop. I usually kept to myself and a few friends during high school, and it went pretty well, the worst I got was annoying harrassment and humiliation. Maybe I was lucky. I was in a private school and most of the people weren't really that bad. And I see a few other year groups at my school who are horrible.
The second thing would probably be do something to intimidate the bullies. Obviously I wouldn't recommend it because firstly it doesn't always work (like you mentioned) and secondly it's garunteed to get you in trouble in school grounds.
I think the best thing to do though would be make a... political fuss about it. Turn it into something profitable. If you force the school to punish them then you will at least be able to get something out of it, especially if money is involved. If it gets on any local news? Probably even better, if you can get to shine them in a negative light.
