a) Kids may send hateful or threatening messages to other kids, without realizing that while not said in real life, unkind or threatening messages are hurtful and very serious.
b) Warning wars - Many Internet Service Providers offer a way of "telling on" a user who is saying inappropriate things. Kids often engage in "warning wars" which can lead to kicking someone offline for a period of time. While this should be a security tool, kids sometimes use the Warn button as a game or prank.
c) A kid/teen may create a screen name that is very similar to another kid's name. The name may have an additional "i" or one less "e". They may use this name to say inappropriate things to other users while posing as the other person.
d) Text wars or text attacks are when kids gang up on the victim, sending thousands of text-messages to the victim's cell phone or other mobile device. The victim is then faced with a huge cell phone bill and angry parents.
e) Kids send death threats using IM and text-messaging as well as photos/videos. (see below)
