netiquette

Netiquette is basically rules for behaving properly online. Depending on which "unspoken" rule is broken it will affect different people in different ways. For example if you decide to bully someone it can affect you, your family, the person on the other side of the screen, and their family. In different situations there are different repercussions. Some good examples of netiquette are treating people the way you would if you were actually face to face with them, also respecting privacy. Some bad examples would be sharing post only with the interest of starting a "flame war".
