The disgusting creatures known as youtube trolls are losers who have nothing better to do than sit on their computers all day and start arguments on youtube. Beware the trolls, as some may unite against certain groups or videos on youtube and their supporters. For example, they may gang up and vote each other's comments up and flag every other comment as spam. They'll then feed off of the madness of the arguments they start. The best way to combat youtube trolls is to ignore them and block them. If they're making several accounts to troll you like the no life douchebags that they are, set your account privacy so only friends can send you messages and comment on your channel. Feel free to report them also.

Protip: make sure your youtube name isn't easy to copy by capitalizing an i or having a lowercase l. Some trolls will jump on the opportunity to impersonate you by creating a new account with a name identical to yours. I've suffered this way. Report the channel impersonating you, and if they were enough of a douchefag they'll most likely be banned within a few days.
Filipinos4islanders: lol ur a fanboy dickrider. UMADBRO?

TheSpanishFilipino: FAGGOT!

TheMexicanInvasion: yeah u fag dickrider y u mad

KoreansDoItBest: LOL FAGGOT NO ONE LIEKS U

*all thumbs up each others comments and flag victim as spam*

note: these are real youtube troll messages I've gotten on a video. Never respond to youtube trolls. It leads to more pain and agony as they suck all the life out of your soul.

Definition - self centered, egotistical leeches that thirst for rage.

Characteristics:
-Mostly child-like in nature (ex. poor grammar, spelling and narrow-minded posts), Trolls may be as they seem, or simply using this childish disguise to provoke more rage.
-Comments are blatantly obvious for the most part, usually sporting a phrase completely opposite of what you'd expect
-Usernames reflecting common annoyances in today's internet culture (ex. "troll3r", "Umadbr0", "l0lf4gz", "itr0llu")
-Not all trolls exist to start an internet riot, a lot of them wait to tear down another users post in hopes of encouraging rage. (ex. "Nice spelling Noob, you obviously are retarded")

Trolls can be good or bad.

Good Troll - "Megadeth Sucks!!" on a Megadeth music video comment section. Obviously a light hearted attempt to enrage people who can't take an obvious joke,

Bad Troll - "Megadeth is overrated, Mustaine is a coward, a poor guitar player and an egotistical pussy. They have yet to gain any fanbase or sell any decent records in decades...sellouts." This is obviously a Troll Comment whose entire purpose is to spark a rage war among every viewer of said video.
YouTube Troll - "Megadeth is overrated, Mustaine is a coward, a poor guitar player and an egotistical pussy. They have yet to gain any fanbase or sell any decent records in decades."
