I have tried to tell people this too I am glad someone else is also saying it. Try to think of it as being on the playground in Grade school. The kids are taunting you from atop the jungle gym. You can take the bait and get dogpiled by the crowd, you can tell the teacher (twitter) and then they come back in retribution, or you walk away. Just like the kid on the playground the troll lives for engagement. Don't feed the trolls
