Reasons why youtube is becoming a troll infested site

In the early days of youtube ,accounts were not linked to gmail so if a viewer wanted to comment they really had to work hard to get their profile verified and then comment.

With the automatic linking and lack of moderation (super for freedom of speech ) the ratio of trolls to productive commenter's have gone up  .

The best example is on music videos .
