Not only are the sources of WolframAlpha curated, they even go the extra step to make sure it's correct. From their FAQ:
"How is Wolfram|Alpha's data checked?
We use a portfolio of automated and manual methods, including statistics, visualization, source cross-checking and expert review. With trillions of pieces of data, it's inevitable that there are still errors out there.
[...]
How is real-time data curated?
Wolfram|Alpha effectively checks real-time data (such as weather, earthquakes, market prices, etc.) against built-in criteria and models. If an unexpected deviation is found, Wolfram|Alpha will normally indicate it, for example by showing lines as dashed."
