If you walk in a room, and a bunch of teenagers are being noisy, do you leave, or call the cops? If your favorite social network doesn't give you enough privacy to avoid trolls, or even abuse, go somewhere else. People complain that trolls have the advantage of privacy, and recommend a police state as a solution. Privacy is a tool. Use it. Don't let anyone take it away.
