Hubot killfile / spam filter.
A pattern-based community killfile for outgoing Hubot messages. Implements a middleware to intercept messages Hubot is about to post, refrains from outputting matched messages.
Perhaps you'd like to prevent Hubot being trained to swear, or you use hubot-twitter-mention but you want to filter out some returned Tweets.
Uses robot.brain to persist killfile entries.
