I haven't been with AH all that long really. What maybe 3 years now? Flew in WB before that. And MSCFS arenas before that (the cheats and such in that place were BAD). Looked at Fighter Ace but declined it. Never upped in AW.
Smack talking IMHO is a big part of the problem. Many of the OLDER players do it from time to time. Most of us don't have a problem with em cause we KNOW em. And sometimes it's funny, perhaps silly, and fun. Thing is some of the younger set in the MA see it and then take it too far. A one up thing?
Not saying everyone should be nicey nice mind you. But i've seen stuff come out on 200 that IMHO INVITES the "attitude".
Lately when they start I've thanked them for noticing me. Not anywhere sure such is the right thing to do, but so far it has shut em up. Pretty sure at some point someone will leap all over the thank you though.
Possible fix? When you see that attitude displayed and know where that person is, UP MANY MANY AND HUNT THEM DOWN.
If that person is flying within your country you might wanna relate that on PM to someone you know as to that location and when that person gets jumped and starts screamin for help a possible reply is "HUH? why DUDE you're all THAT! RIGHT? so handle it

I'll just watch and learn from what I see

Possible fix but ???????? Sort of a self policeing thing?
hmmmm.............Might be a totaly bad idea. Not sure there is a GOOD answer.
But it could create so really intense furballs?
