People’s opinion vary greatly on social network sites.Some are in favor of those sites for they providing many opportunities to know other people and to know what’s happening in the world. Besides, they think network websites are very convenient to make friends. But some people think it is difficult to protect users’ privacy on social network sites.Some even get addicted to them and abandon their real life. After all, they don’t live in the virtual world.For example there are so many personal information disclosure emerging from cyber love.
