Well, I'm more of the mind if you don't like someone shooting you in your parrachute, camp out above their airfield and use selective vulching tactics to show your disaproval.
You could even get your message accross with a open message of "Take that you dirty Chute Stooter!!" as your bomb is about to hit!
I'm sure some will find it petty and childish behavour, but revenge is a dish best served cold!
Cheers!
