The more appropriate term for the idiotic YouTube user, VenomFangX, who makes uneducational videos that will reduce your intelligence just by watching them.
"Hey, did you see the latest crap from VenomFagX on YouTube?"
"Yeah, and if I didn't know that he was an idiot already, I'd probably have died from *headdesk*s."
The best way to deal with a troll is to not feed it. That's why the trolls' dilemma exists.
It is basically an insistence on the person being addressed (or group addressed) to respond or be considered defeated.
The urge to not have a default to defeat is strong for many, and so the trolls' dilemma may easily get a response.
This is the dilemma, though. To respond, the troll wins, but to not respond, the troll scores an arbitrary and often false 'victory'.
It is often used as a last resort once the troll has been exposed, or as a strong opening bait to hook the victims early.
"You all know deep in your hearts that there are secret alien organizations in our governments working against us all. You won't answer me, though, because you know it's true. You're afraid."
-- This is merely one way of using The Trolls' Dilemma.
