we did have about 80 matches over 2 years, only 3 had some afters.
the few vs jg11 was the first, they requested axis vs allies, and called us out for HO ing which was nonsense especially with more manoeuvrable aircraft. the drubbing was too much for stampf to take after he built it up to be some sort of epic show down. JG11 left.

KN vs JJ from all accounts JJ's got a few aggressive kills in the merge and caught KN by surprise, HO ing wasn't against the rules at any point even though some started adopting this tactic to get an advantage.

I had to kick out KN because of the posts and not because I didn't agree with them.

Bone then made the pigs leave by sending them nasty PM's that I didn't know about. Had they made me aware of what was said at the time I could have taken corrective action but they just assumed because I was in charge it would have been swept under the carpet.
Pigs vs LD The pigs or rather junky and krup decided to take more than 25% fuel and climb, again nothing in the rules regarding this and they proceeded to get chased around by angry LD's who in one round ran out of fuel and had to bail. I was in the DA at the time to watch and was asked by krup and dhyran what the rules were on this and gave them as I knew them which was fuel loadouts are the pilots choice. Again accused of not acting in the correct manner
back in FA we had squad fights every weekend and they did have a host which in hindsight was probably the best policy just incase things spilled over. No-one questioned the host/umpire/referee and that kept things in check. Shouldn't have too but I guess that is just human nature.
The other issue was bringing MA squabbles into it, when you have a perceived view of a group of players and you have the opportunity to fight it out there is always more to a grudge match!
