Why even let it bother you to the extent of posting about it on this forum, Just suck it up and move on to another server. so what if they're arrogant, it's their server which they've made available to public racers and they reserve the right to be ****s, if they like.
I've not been in the community long, but one thing I've realised so far is that LFS is a has grown from a very small group of people, which means that if you're new, or not part of a clique, then you're better off just throwing on an extra layer of thick skin and learning to race well, otherwise you'll just be in the way and then people crash into you, or you into them, then they call you a noob, and you get pissed off, then you think they're being arrogant and give them lip on their server, then they ban you.
I'm not saying that's what happened with you as I don't know what you were banned for but I've seen that happen on servers.
