W6. How important is it to be civil online on the Internet?

We always meet a large amount of people in the imaginary world what we called "the Internet". We usually can't see their shape. They just exist their imaginary name(like user name, ID), and their actions (like comment, or mention...). And we also be showed about ourselves like that to other Internet users. So we always don't have enough information to others. So we need to be civil to consider this situation. If we have come into conflict with other people in the Internet, it is hard to resolve the problem. So conflict will accumulate and the Internet world will fall into confusion soon. And sometimes this problems come out the real world. Some conflicts can be the real crime. Of course, I give the extreme example. But it happens quite frequently. So we should be careful using the Internet.
