How was this question not flagged as unrelated to information security? The main problem with stackexchange (aside from closing your questions) is not knowing how they will interpret their own rules.
That's because flagging and rule application is not centralized. Once you have a certain number of points from helping others, you get the right to flag questions. Not everybody does is correctly right away. But over time and on average, its a pretty good system. Better than having mods that may ego trip or follow some personal agenda. Also, if a good question gets closed, other users can flag it to be re-opened.
