Skeptic vs paranormal subreddits
================================
Classify a reddit as either from Skeptic subreddit or one of the
"paranormal" subreddits (Paranormal, UFOs, TheTruthIsHere, Ghosts,
,Glitch-in-the-Matrix, conspiracytheories).
Output label is the probability of a paranormal subreddit.
