Differnt people have different purposes of communicating with others online. some are postive and others are negative. There is a bad joke says that when you think that you are just chatting with a charming woman ,but on the other side of the internet, there is a raunchy man is rubbing his smelly feet while chatting with you. Maybe you will transfer some money to your "sweet baby" sooner or later, then "she" delete you from his friends list. This is something we are alway taught in order to avoid frauds. But most time, we talking with our friends online without any concerns. We share the same hoobies and built a lot of group chats to communicate with each other. We share the good things and learn some good experiences from others to improve ourselves on various areas. So, is online communication bad or not really depends on what you want from it. If your purpose is nagative, you can't blame being defrauded!
