Automatically block users with the default profile image (eggheads) who @reply you. Super simple. Will probably be expanded at some point if I have time.

block_eggheads.js

var Twit = require('twit')

var T = new Twit({
	consumer_key: '...',
	consumer_secret: '...',
	access_token: '...',
	access_token_secret: '...'
})

var track = '@ws' // Also try 'trump'

var stream = T.stream('statuses/filter', { track: track })

stream.on('tweet', function (tweet) {

	if(tweet.user.default_profile_image){
		T.post('blocks/create', { user_id: tweet.user.id }, function(err, data, response) {
			if(err){
				console.log('Error blocking @' + tweet.user.screen_name)
			}
			else {
				console.log('Successfully blocked @' + tweet.user.screen_name)
			}
		})
	}

})
