I haven't experienced too many people like this on here but there are some. Honestly us private scripters all have a group chat and get along. Even though we're in competition for scripts, we don't fight over them and actually help each other. I hope the same can be said for other services like questing/skilling.
I also have a chat with other gold farmers and most are friendly and willing to help. Of course you have some that want to keep all the secrets to themselves and throw everyone else off track. But that happens with everything in life. Gunners as you call them
