Are there any other initiatives (other than the proposed code of conduct that failed) that seek to stop internet harassment?

Has there been any research on the effects that social media has on individuals with respect to ‘trolling’ as well as any other accompanying negative behaviors and why are these behaviors manifested in some situations but not others? Is it ultimately the anonymity that prompts people to act in negative ways?

What is more prevalent, the organizing of groups as Shirky pointed out, or the ‘troll’ behavior brought up by Lanier?

What does the future look like to Lanier, what are his predictions for what is to come with the web?
