I like snopes, and even look to it regularly, but in many cases the authors biases are clear (and I'm not even talking about in politics).
For paranormal phenomena, which honestly should be classified as "unproven" or "legend" (categories that they do have) they often classify it as outright false.
But they do do their research much of the time, and are especially good for debunking pictures of "real" animals as they can often find the source of the picture before it was edited, or as a fantasy art piece not claiming to be real.
