In defence of that forum, which I have visited very rarely, when I have had a technical issue with Swift, I have always had good and detailed responses, sometimes from Swift themselves, and I found it a good medium to get in touch with Swift as their customer service telephone leave much to be desired.
And the thing with bullies, they only get away with it if you let them. Sometimes these forums are very much like the school playground, thankfully not this one, and they all like to have their little gangs, usually because they havent the confidence in themselves to just be themselves.
As has been said, we have two excellent moderators here with two very different styles and both work well. I wouldnt be worried about the little keyboard warriors coming here, or lasting.
