Mi Lan loves to buy clothes from Taobao. It saves time and sometimes you can find really cheap goods.

After a recent online shopping, Mi took photos of some of her most satisfying goods and put them to a lifestyle forum(论坛) on Tianya.cn. The 25-year-old hadn’t expected it would be the beginning of a nightmare.

The returning message Mi received were unacceptable. “You call this fashion? How old are you? 50?” read one message. Another accused(谴责) Mi of advertising for these clothes: “Get out of here with your ugly goods! Don’t waste people’s time!” Yet another message questioned Mi’s money situation, saying the clothes looked cheap but that even poor people should have a better fashion sense.
     “I just wanted to share my online shopping experience,” said a deeply red-faced Mi, who deleted her photos from the website the next day. “But now I’ve lost confidence in my image. None of my friends told me before that I dressed in bad taste. Why are people so unkind online?”
     Why? We used to think that people are rude online because of hiding behind anonymous(匿名) situation, we feel like we can get away with anything. But since the rise of social networking sites, we are not as anonymous as we used to be.
     Still, rudeness goes everywhere. Sina’s Weibo, for example, requires users to register(注册) with their real name, yet people do not shy away from using dirty words whenever they disagree with each other. It is worse with some famous people and so-called “public stars”, some of who might even use personal attacks(攻击). Politeness and good manners do not get you noticed on weibos, but strangest and most impolite words will.
     Scientists and researchers have tried to find out why we do wrong things when using social websites. According to a Wall Street Journal article, recent research suggests that visiting social networking sites brings down our self-control.

This is because most of us present a beautified image of ourselves on Facebook or Weibo. This good image and the encouragement we get from good words uplift our self-respect.
     But when we are too proud of ourselves, we might show poor self-control. It’s a bit like drinking: wine might make us feel good, but too much wine harms our minds and makes us lose our self-control. Many people forget that they’re speaking out loud when they communicate online, especially when posting from a smart phone.
