Many people think that a game like Second Life is better than real life. They are wrong and right at the same time.
They are right, because you just can go away if someone bothers you.
But they are also wrong, because people are people and ever the same. And in SL many people are on a even more rude behaviour than in RL because of the (false) anonymity an avatar gives you. Many are trying to do things in SL, which they would never do in RL. This is part of the charms of the game and of course not bad, but there always some people who cross the line, then. And this is bad.
