Stack Overflow has a vigorous moderating policy. That's usually a good thing. It helps form a community, and keeps stuff out.

The problem comes with a huge site like SO, because there are so many "not welcome here" topics which get closed, with no suggestions about where to put those questions, and without great explanations about why those topics aren't welcome.

It's not as thoroughly toxic as some[1] aspects of wikipedia are, but it's not pleasant for some people.
