YouTube

YouTube (www.youtube.com ) is a video sharing site, and a great place to troll. YouTube was created back in 2006 by some guys that no one remembers the name of, probably because YouTube is now owned by Google. About 1/7th of the world uses YouTube and 100 hours of video is uploaded per minute. There are millions and millions of YouTube users. YouTube users have the tendency to argue, fight, start flame wars, or just be a dick to each other. Because of the large amount of users, the large amount of content on the site, and the fact that there are no moderators, YouTube is a great target for trolling.

Trolling on YouTube
Most trolls start their carrier on YouTube. The site provides plenty of material to troll, or to use for trolling.
 * Comments: Comments are messages posted under videos or channels by YouTube users. Comments also have a rating feature, where users can give the comment a "thumbs up" or a "thumbs down". Comments with a higher rating are displayed above lower rated comments, until their replies become less and less inactive.
 * Replying to comments: Comments can have up to 500 replies (there can be more if flagged comments were restored). If a comment is constantly getting new replies, it will be displayed higher than comments that do not get frequent replies, regardless of the rating. This makes for great trolling opportunities. For example, you can post a comment that outrages people, and you will get tons of hate replies. All these replies will move your comment closer and closer to the top, and your troll comment will be one of the first seen. You will be satisfied by the successful troll.  
 * Videos: Uploading videos can be a tool for trolling too. For example, you can upload a video with a promising title such as: "Cat does backflip while riding unicycle". Then when the user clicks on the video, it is not what the title promised, such as a Rickroll.
