We recently allowed questions to be closed, but it is not being used properly in most cases and limiting participation. We have removed this feature.
If you have a question you want closed, just let us know in the "Ask KidzSearch" section and we will review it. In most cases, the only reason we will close a question is if it is getting out of control or having too much fighting going on with it. In certain cases we will also close one if the question might reveal too much personal information in the answer or post. Closing it is our way of explaining why it was not allowed. If we just removed it you would not know the reason.
While we don't encourage it, If you posted a question and really don't want it to be seen, you should hide it.
