This is the internet and this is a free public server. Play any public game and you will find this sort of thing, particularly worse on free communities. A close knit community works much better, and all round has a better aptmostphere. There are arguments and disagreements but by in large they pale in comparison to the drama on these forums.
The larger this community gets, the worse it is going to get. Roleplaying communities work best small scale. Discovery has become the largest Freelancer mod, and thus attracts all the new players. Short of turning this into a closed community, I don't see any solution to all our problems.
And we already know that is not going to happen. Any change we make will benefit one group of people while harming another, there isn't a middle ground unfortunately.
Personally I'm choosing to take everything that happens in stride, and try to be better to other people in general. I don't expect anything in return, but I'm going to ask that whenever someone does anything kind to you in game, you will repay the favour by doing three kind things to other players in the community. I think there was a book or a movie about something like this at one point, it's a good concept.
