Hi, I am an occasional user of your forum, and am curious how people will react to the question: Do You Consider This To Be A Friendly Community? It wouldn't take long to find examples of both the good and bad, so let's keep it simple.
Yes, definitely the community will reciprocate what you're given to them. If you are harsh to the community, they too will be harsh to you, and if you are using Bitcointalk the way it is intended to be and you follow the forum's guidelines you will have a pleasant experience.
Hehehe...first, the community here means the entire members who form the forum and not the forum's rules or admin, so I see less of the practicality of what you wrote as far as this community is concerned.
You don't have to be harsh for some people to be harsh to you and you do not have to be nice for some people to be harsh to you. What matters is to do your thing, obey the forum rules and not care about what anybody says, ugly behaviour is everywhere, it's merely a noise, otherwise, you might hurt yourself. There are enough of them who would make sure of that.
