I have been an active member of most of the websites of Stack Overflow for the last couple of months now. In this time I have never seen an inappropriate post of any kind.
By inappropriate I mean a post that I can flag.
I have seen some websites where posts need to be approved by the admins etcetera, but this is not the method used here.
Is the SO community just so fast that they remove everything bad before other people can see it? Or are the people that post here just genuinely nice people?
