What does the Bible say about Internet Trolls?

[Ab Cd]

Are there any specific lines you can quote from the Bible about people who troll around on internet forums like this one?
And don't tell me there isn't such a line in the Bible. That would be suggesting that Jesus never encountered some obese unemployed 30 year old bum living in his mother's basement and entertaining himself by posting rude and explosive comments over the internet. And surely Jesus Himself would have encountered internet trolls on Facebook and when He hung out on religion forums like this one.
