There is a great "Wander Over Yonder" episode with feeding trolls. Everyone should watch it. If you don't respond and ignore - trolls go away! Simple as that. Every time you quote a troll they win! Every time you respond to a troll they win! These people have no lives and no families and no mothers or fathers. The have a dull existence. Let them fade away!
