You see those spaces between the posts? There's hidden subliminal messages there telling everyone to behave or face the ban-hammer-o-doom.

I've been a part of a lot of gaming communities and have noticed something. Official forums will always have flamers, whiners, trolls, and jerks. They don't tend to go into guild run forums because they know the mods won't tolerate anyone harassing any member of their community. Guild forum communities are full of people who get along with each other and it's easy to form friendships.
When you get into a game with hardcore mode players things change. A hardcore player will give you the armor off their back if you need it because they know that one day they will need someone to help them. It takes a special kind of person to play hardcore mode, which is what makes the community so great.
